You finally decide to switch feed companies. Maybe the price jumped. Maybe availability got unreliable. Maybe a neighbor swears by something different. Whatever the reason, you've made the call, and now you're wondering if the next few weeks are going to be rough.
They don't have to be. But they can be, if you rush it.
At Kreamer Feed, we've been manufacturing poultry and livestock feed since 1947. We've also watched what happens when producers switch feed brands too fast, and we've helped plenty of retailers and farm families work through transitions without the production dip that people sometimes dread. Here's what we know.
Why Switching Chicken Feed Can Disrupt Your Flock
The short answer is: chickens are creatures of habit, and their digestive systems are more sensitive than they look.
When you switch feed companies, you're almost certainly changing the ingredient profile, even if both products claim to meet the same nutritional specs. Different corn sources, different soybean meal suppliers, different vitamin premix formulations, and different processing methods all result in a finished product that smells, tastes, and digests a little differently than what your birds have been eating.
A study published in BMC Veterinary Research found that the effects of switching feed types on the microbiota were larger than the effects of age, suggesting diet transitions have a significant and measurable impact on the gut microbial community of chickens. In practical terms, this means a feed change is a bigger event for your birds than it might feel like from your end. A little planning goes a long way.
The Transition Timeline That Actually Works
The standard advice is to transition over seven to ten days, and it's standard because it works. Here's what that looks like in practice.
Days 1 through 3: Feed roughly 75 percent of your current feed mixed with 25 percent of the new feed. You're introducing the new product at a level that's noticeable to the birds but not overwhelming. Most flocks handle this without any visible reaction.
Days 4 through 6: Flip the ratio. Now you're at 50 percent old feed and 50 percent new. This is usually where any resistance shows up if it's going to. Some birds may eat a little less during this phase. Don't panic. Watch water intake and general activity level rather than fixating on whether every bird is enthusiastic about the change.
Days 7 through 10: Move to 25 percent old feed and 75 percent new. At this point most birds are well adjusted. Keep a small amount of the original product in the mix as a bridge rather than pulling it completely.
Day 10 and beyond: Full transition to the new product.
If you run out of the old feed before the transition is complete, don't just flip the switch and hope for the best. Contact your supplier and get a small amount to extend the process. A rushed transition over four or five days is better than an overnight switch, but it's still not ideal.
Layer Feed Transition: A Closer Look
Layer feed transitions deserve their own conversation because egg production is one of the most reliable indicators of nutritional disruption, and it's also the number that retailers, suppliers, and producers watch most closely.
When you're changing layer feed brands, even between two nutritionally similar products, expect a possible short-term dip in production. This is normal. It doesn't necessarily mean the new feed is inferior. It often means the birds are adapting. Eggshell quality can shift temporarily as well, particularly if the calcium or vitamin D3 levels differ slightly between the two products.
A few things that help during a layer feed transition:
Keep free-choice oyster shell available throughout the switch. It gives hens a way to self-regulate calcium intake while their bodies adjust to the new ration. Monitor shell thickness and production numbers daily during the transition period rather than weekly. Catching a trend early lets you slow the pace if needed. Avoid stacking a feed transition with other changes in the flock's routine. Moving birds, adjusting lighting, or introducing new animals at the same time compounds the stress load and makes it harder to know what's actually causing a problem if one develops.
What to Check Before You Switch
A feed transition goes more smoothly when you do some homework first. Here's what's worth knowing before the first bag of the new product arrives.
Compare the guaranteed analysis. Look at protein, fat, fiber, calcium, and phosphorus levels between your current feed and the new one. Significant differences in any of these, particularly calcium for layers, mean the transition will require more careful management. Small differences are easier for birds to absorb.
Look at the ingredient list. If the new feed leads with corn and soybean meal the same way your current feed does, the adjustment will likely be smoother than if the protein source or energy base is significantly different. Major ingredient swaps mean a longer transition window.
Ask the manufacturer about their formulation. A feed company that can clearly explain what's in their product, how it's tested, and where the ingredients come from is worth more confidence than one that deflects those questions. At Kreamer Feed, that conversation has always been one we're happy to have. Transparency isn't a marketing line for us. It's how we've built relationships with retailers and farm families since 1947.
Check the feed form. If you're switching from pellets to mash or vice versa, factor that in. Feed form changes can affect intake and waste patterns in ways that feel like a production issue when they're actually an adjustment period. Give birds extra time when form and brand are both changing at once.
What to Watch During the Transition
Even a well-managed feed switch deserves close observation. Here's what to keep an eye on.
Feed intake. A temporary dip is normal. A sustained drop over more than three or four days is a signal to slow the transition pace.
Water consumption. Birds that aren't drinking adequately aren't digesting properly. Water intake often drops alongside feed intake during stress periods, which compounds the nutritional shortfall.
Droppings. Loose or unusually colored droppings during a feed switch usually reflect the microbiome adjustment. They should normalize within a few days. If they don't, or if you see signs of actual illness, that's a different conversation.
Egg production and shell quality. For layers, these are your most direct feedback. A short dip followed by a return to normal is typical. A sustained decline that doesn't recover after the full transition is complete suggests the new feed may not be delivering what the label claims.
Body condition. For longer transitions in broilers or livestock, keep an eye on weight and general condition. Birds that look like they're losing ground during a transition need either a slower pace or a closer look at the new product.
When to Think Twice About Switching
Not every reason to switch feed companies is a good one, and some timing is better than others.
Switching during peak production periods or in the middle of a laying cycle adds risk without obvious benefit. If your flock is performing well, a feed transition that saves a few dollars per ton may not be worth the production disruption and management attention required to do it right.
If the reason you're switching is because your current feed seems to be underperforming, look carefully at what's actually causing the problem before changing products. Feed storage conditions, feeder access, water quality, flock health, and lighting all affect production independently of what's in the bag. Switching feed to solve a problem that isn't actually a feed problem wastes time and risks creating new disruptions.
The best time to switch is when production is stable, when you have enough of the old product to run a proper ten-day transition, and when no other major management changes are planned for the same period.
Frequently Asked Questions About Switching Chicken Feed
How long does a feed transition actually need to take?
Seven to ten days is the standard for a full transition, and it holds up in practice. If you're changing both feed company and feed form at the same time, lean toward the longer end of that window. Faster transitions are possible, but they carry more risk of a production disruption.
Will my hens stop laying when I switch feed brands?
Not necessarily, but a temporary dip in production is common. Most flocks return to normal production within one to two weeks of completing the transition. A well-managed ten-day switch usually minimizes the size of that dip compared to an abrupt change.
What's the best way to mix old and new feed during a transition?
Mix them in the feeder or bucket before offering, rather than putting one on top of the other. Chickens will sort through a feeder and selectively eat what they prefer, which defeats the purpose of a gradual introduction.
Should I add vitamins or supplements during a feed transition?
Adding water-soluble vitamins during the transition period is a reasonable precaution, particularly for larger flocks or during transitions that coincide with other stress factors like weather changes. It's not always necessary, but it provides a low-cost buffer during the adjustment.
Does it matter which direction I transition, old to new or new to old?
The direction doesn't change the principle. Gradual is always better than abrupt, regardless of which product you're moving toward. If you're ever moving back to a previous feed after a failed switch, the same ten-day process applies.
How do I know if the new feed is actually working after the transition?
Give it at least four to six weeks after the full transition before drawing conclusions. Production, shell quality, body condition, and feed conversion all need time to reflect the new nutritional baseline. Judging a feed based on the first two weeks after a switch mixes up transition effects with actual product performance.
Final Thoughts: Slow Is Fast When It Comes to Feed Changes
The producers who handle feed transitions best are the ones who plan ahead, move gradually, and watch closely. A ten-day transition feels slow when you're eager to get onto the new product. But a production dip that takes three weeks to recover from is a lot slower.
