This thread was still fresh in my memory tonight,thus my reply.We just finished up our weekly hatch here and I had 2 stragglers,one was an egg from Thang,the other was an IB egg.All the others in this group was out and dry by Tuesday nite. Thangette was pipped last eve and was out drying off this morning.I noticed one IB egg that was pipped Thursday eve as well but really didn't pay a lot of attention until tonight when I took the new Thangette out and zip tied for identification.
The IB egg was pipped on the pointy side.Chick was alive and chirping but had made no progress since the night before.So,I began to break some shell away but noticed fresh blood on either side of the pip. Every 2 hours I chipped more shell away until finally around 10pm tonight was able to break over half the shell away when blood started dripping badly.Needless to say the peachick did not make it but while looking at it's legs and feet,,all toes on each foot was backwards,just as your peachicks was. The legs actually had a bend in the lower 1/2.The chick would have never been able to walk normally,even if it would have survived being helped out 100%
I believe that chicks that pip on the wrong side of the egg will have this problem with backwards curled toes and somewhat curved legs.Obviously your chick survived hatching but when I noticed the toes curled backwards,my chick really couldn't even turn inside the egg.Quite possibly from being in this position prevented the blood from making it's way inside the peachicks body as well.
I've helped many peachicks out before and have hit live blood vessels manytimes and know when to stop peeling,ect but this chick with absolutley no blood coming from over 1/2 the shell being gone,then to several large blood drops suddenly pouring out is strange.There appeared to be a small airsack still at the large end of the egg but on the pointy end it wasn't really an air sack-per say,,more like available space caused when the membrane elongates pulling away from the inner shell.If this peachick hadn't broken a hole thru the shell it would have suffocated rather quickly with such a small amount of air available to breathe
