Hello... I'm "new" to the forum, but not new in that I've been reading for a couple of years (4) and we have a nice flock of various breeds of chickens, both standard and bantam. On Monday, my husband came in from letting everyone out of the coop into the run, with a baby chick in his hands...the baby had escaped the nest box 3 feet up, and was marching in line with the others to go outside! We have 3 nest boxes and 2 Bantam D'Uccles sitting in one box, a Buff Orpington in another, and a Barred Rock in the 3rd. We tried the with D'Uccles to see if one of them was the Momma, but no, they pecked it, so we brought in the Buffy and she went straight into Momma mode: clucking, fluffing, and allowing it to run under her. All was/is good. Two days later, he heard another cheep cheep from the eggs in the nesting box - which after Monday we dated with pencil to try to keep track of what was going on. Brought that egg in, with a small pip, put it under the Buffy, and about five hours later - Another beautiful little chick, which she cooed, and fluffed up for and all was and is good. So today, we find yet another egg which is cheeping, but no pip. We bring it into the dog crate where Momma and babies are, and put it under her. All is good for about an hour or so, then I hear a distress/painful cheep and look over and Momma is pecking the heck outta the shell (no previous pip). Not knowing exactly the process (if the momma should be assisting or not), I wait a little bit before taking action. About 15 minutes goes by and I hear the distress cheep again and Momma is again pecking the heck outta the shell and now I see a little bit of baby chick and some blood. So we took the egg out and in ignorance, try to peel away the shell.... it was not easy, but the little chick was breathing and eyes opening and closing. I then got on line, came to the site, did some research, and realize that both Momma and us jumped the gun in trying to release the chick. We now have it on damp paper towels, in a separate box, with a heat lamp close by. Is there anything else we should do? Anything else we can do? I do not see an egg yolk sac, but part of the shell is still on, and that is the part around the bottom. We are not going to touch anything else. Is there anything we should do? We cannot see it breathing, but if we move it slightly by moving the paper towel it is lying on, it does slightly open its eyes. At what point do we give up? How can we tell when to give up? And, if we do, what action should we take to painlessly allow it die? Thank you all for your help.
