Chickens have benefited from milk proteins in diets for many years, study after study.

"Skimmilk and Buttermilk are Excellent for all Classes of Poultry but especially valuable for young chicks, laying hens and fattening birds. Milk supplies the vitamin riboflavin which is indispensible to high hatching quality in eggs. As a desirable protein supplement, milk undoubtedly heads the list."
Milk replacers are sometimes used to prevent outbreaks of enteritis. The key to using milk products is not overdoing it.
