I received a request to post something about yogurt and chickens as I understand there is some question on here about whether or not to give it to birds.
Please see:

Here is the gist of what was said by Dr. McCrea who is on Peter Brown's (aka The Chicken Doctor) Forum:
Dr. McCrea: "It was not a good idea to give dairy products to your poultry unless your goal was to induce diarrhea. Chickens do not produce the enzyme Lactase and so therefore cannot digest lactose (the sugar found in dairy products). Dairy products are fine as a probiotic for humans but are not suggested for use in poultry."
Me: "when you say "dairy products" are you referring only to the milk and cottage cheese that I mentioned above or would that also include yogurt? It appears to be a widely held belief that yogurt is a good probiotic for chickens and I have read that it contains lactase enzymes which digest lactose."
Dr. McCrea: "Poultry do not produce the enzyme Lactase and therefore cannot digest the sugar Lactose. All dairy products contain Lactose, including yogurt. Yes, there are beneficial bacteria, but they are designed for humans, not poultry. You will still induce diarrhea and that will not allow the "probiotic" bacteria to attach and perform many of the beneficial functions that we humans enjoy. This is yet another case of people not consulting with their poultry specialists. Stories are spread via the internet and hearsay that are not based upon scientific fact. Always consult with your state poultry extension specialist or poultry extension veterinarian."
I understand there are many folks who wholeheartedly believe that yogurt is fine to give birds but I have to defer to Dr. McCrea since she appears to be an expert - at least the most qualified "expert" I've run across so far. Here is what Peter Brown says about her:
"Dr. Brigid McCrea Phd., is Extension Poultry Specialist at Delaware State University in Dover, DE.
Dr. Brigid McCrea is a poultry extension specialist who specializes in small, medium and backyard poultry flocks. She is located at Delaware State University in Dover, DE. Dr. McCreas interest in small flocks began with her career in 4-H poultry and she has been interested in doing research for the benefit of small flock owners since that time. She received both a B.S. and M.S. degree in Avian Sciences from the University of California, Davis and her Ph.D. in Poultry Science from Auburn University.
She began the Small Flock Education Series or Way Cool Chicken School, as well as COOPTASTIC!, as a means of fulfilling the educational needs of her small flock clients. Her research interests include work on natural remedies for parasites (both internal and external). Additionally, she is interested in research on management issues for niche market poultry commodities (i.e. pastured poultry, organic poultry, free-range poultry, game birds, squab, waterfowl, etc.). Dr. McCrea frequently receives telephone calls from flock owners, as well as city officials, on the topic of changing ordinances to permit the keeping of small flocks, often in urban or suburban settings.
Dr. McCrea encourages a common sense attitude, use of Biosecurity principles, and educated decision-making as a means of keeping your flock happy and healthy. Dr. Brigid McCrea may be contacted by telephone at 302-857-6432 (preferred) or by email at

I hope that helps.
God Bless,
