Hi, sheribee - sounds like you've been pretty successful with the incubator! What I do, when I hatch chicks in this way, is to take the newly hatched ones, once they've dried off, out of the incubator and pop them under a heat lamp in a brooder box, so any late-comers can hatch out in peace. You don't say what type of incubator you have, so it may be that's why they're all in together. If you can get a heat lamp and a brooder box then that should solve the problem. Have the lamp about a foot to 18 inches above the chicks. If they all congregate under it all the time, they're too cold, but if they try & get away from it, they're too hot & you need to raise the lamp a bit (it's all common sense, really). Chicks don't normally peck at each other (are you sure you haven't got a baby owl in there by mistake? lol !) and I've never had any come to any harm from leaving them in with their siblings. Sorry can't offer any more constructive advice, but I hope this helps. K x
