Just got 4 little ones last week. Everything is going ok, but how do you socialize them? I don't want them to feel harassed, but when I put my hand in the brooder, they run! I tried giving them one small spinach leaf torn up and they seems to like that--but is it ok to even give them anything other than chick food at this time? I read you should play with them in the first 60 days--but sorry, I don't know how to play with a chicken...help!
