This morning while checking on my incubator i heard something peeping! I could see a little chick in there! The thing is though he is three days early and i dont see any sign of the others hatching yet. Is it okay to keep him in the incubator? Should i put him the brooder alone? Also he has a red bump thing on his butt, almost like were he was attached to the eggshell. Is this a bad thing? HELP PLEASE!!
