Ok, I've seen a post about how yogurt will help increase the production of eggs. But then, someone posted that it's false and yogurt is actually harmful to chickens. I'm confused now. I want to see a increase in my eggs, but don't want to harm them either. Thoughts please?? This is what I found posted....... Please be advised that feeding yogurt to hens will NOT, can NOT and does NOT increase egg production! The truth is: chickens are not naturally equipped to digest milk sugars and yogurt can cause diarrhea leading to further health problems. The primary influences on egg production in hens are proper nutrition, lighting conditions and stress. To optimize egg production, feed your flock a complete commercial layer feed, clean water in clean containers, lots of clean, dry living space and practice good biosecurity. There are NO SHORTCUTS to optimizing egg production and hen health should always be the foremost objective in caring for backyard chickens. edited to add: Some yogurt in small amounts occasionally will not hurt a chicken, but poultry probiotics are a much better strategy if improved digestive health is the objective.
