I understand that in France the La Bresse chickens are fed a diet that consists of milk and other diary products. Can chickens digest it? can they even make use of the contents of milk? I mean take snakes. There's this time of the year that people in India feed milk to snakes but they can't digest it and usually end up dying. I've read somewhere else that chickens don't even HAVE the right enzymes to digest milk but surely it won't harm them right? I mean they've been doing it for ages in France. Would it be safe for me to try it at home with my La Bresse?
