This is not for the squeamish...this is what I am dealing with........
ok.. that's not good.. so prepare yourself for the fact that you may very well lose the little guy..
I can't really tell if that's just yolk or if there are also intestines there.. if it's just yolk you can coat it with something like neosporin (the kind without painkillers) to help keep it moist
either way that's a lot which wasnt absorbed.. it's very prone to rupturing especially if the chick is trying to move around alot.
I checked with the emu farmer's handbook.. they say that once moistened with the ointment that you can carefully push the yolk inside the chick's body and then it can be wrapped with plastic wrap which has been smeared with whichever ointment you decide to use.. however there is still a good chance that the chick won't survive.. (the plastic wrap is recommended for chicks who have yolk outside of the body that is
smaller than the size of a small apricot).. they say that it can be held in place with a bandage..
if the yolk is aboutthe same size as a small apricot they say the chances of survival are greatly reduced
either way if you do decide to try to help the chick make sure your hands are as clean as possible (use something like betadine to wash them)
they also recommend looking for an underlying cause .. with as red as the area around the chicks eyes look in the picture it points (to me anyway) that it was caused by a lack of oxygen..
I found the info on page 125 & 126 if that helps any
