I want to put my two month old in with my two hens, and they don't mind him or her, actually they like him/her, but is it too soon for it to eat lay mash? I heard that large amounts of calcium does bad things to a young chicken, but I forget what. Anyway I cannot tell if it is a boy or a girl, can roos eat lay mash? So basically the question is: whether or not it is a boy or girl can it go in wih the big chickens? Will the feed hurt it? Thank you for reading!
