I have a chick that seemed to be having a hard time hatching. It is 3 days late. It had pipped but nothing else for hours. Only a very weal chirp. I could barely feel movement. So I chipped away at the shell and left the inner sac in place except around its beak, then wrapped in in a warm moist papertowel and put it in the incubator to see if it tries to get out of the sac. There is no yolk at all. The cord is intact still. That is where I left shell. I didn't want to pull it off there. It will chirp and move a little but is not trying to to much but a kick every now and again. So I pulled the sac away except where the cord is at its bottom end, rewrapped it and isolated it in a small plastic container and is sitting on a heating pad. Right now the temp in there isn't warm enough, its at 81 but climbing but the humidity is 86%. I supposes that is becasue of the wet paper towel. It is still listless but i'm hoping when I get the temp up to about 100 that will change. It probably didn't have a chance in the first place but I wanted to do somethng to help. I never leave them to die in the shell. I have only lost 1 chick that I helped out and thats not bad concidering that i've helped out many. I was hoping somebody had some advice as to what to do to help this one get more lively. It is breathing fine and like I said gives out a little chirp every now and again. It is alive but I think in critical condition.
