Have another question for everyone. I got 3 white chickens today. They seem to be around a month and a half old roughly. The lady I got them from wasn't for sure what breed they were let alone how old they are. She gave me a little bit of feed for them and for some reason had some baby chick crumble on the bottom of the jar and filled the rest with a broiler mash. I am going to use these chickens for egg laying if I end up with any hens so I'm wondering what kind of feed to give them. Can I keep them on a broiler mash or switch them to a different feed? Thanks again.
