I currently have 13 one week old chicks in the brooder. They are doing well. They currently have some limbs for roosting and I've been feeding them chick starter along with a scrambled egg here and there and some yogurt. What else do they need? I read somewhere about having a dust bath for them? How do I do this? Also, do they need grit of some kind? Any other tips and advice are welcome. Merry Christmas!!
