I have 4 baby chicks 3 or 4 days old which I got on Monday( the 23rd). They are all doing fine. Im feeding them Purina non medicated chick starter. No grit yetbut my husband did give them about one or two worms each day. Little worms which he raises organically. They haven't had pasty butt. They are energetic, and seem otherwise healthy. They don't seem to like the temperature much above 90 because when I keep it at 95 they all stay ion the edges to sleep. Is this dangerous. Should I feed them grit because of the worms. The other 3 chicks have normal poop. Any suggestions?
