A week ago I bought 6 chick 3 are ISA Brown and 2 are barred rock and the other is black but I can't remember what kind. Right now I am keeping them in my made up little pen with a heat lamp. I try to keep the temp in there between 80 & 90. (Please if this is not right correct me, I won't be offended) I can't decide how old they are the are well into the development of wing feathers and some have tail feathers coming in. I have also noticed that they each have a tiny little comb. I have been researching everything so I can get this right. I have even done the 1tbsp acv to 1 gal of water. I am up for any pointers.
