Just had my first ever hatch tonight! Two chicks hatched within a few hours of each other. I removed them after a while as humidity was so incredibly high they couldn't fluff up. When I removed them I added a wet sponge to ensure humidity didn't crash. Regardless the third chick, that had externally pipped and zipped half way, but had not been progressing at all became stuck and exhausted. I could see the membrane from outside and it looked incredibly dry. The chick was trying to hatch, but the zip was incomplete! After a number of hours and as the chick was getting weaker, I wet the uncovered membranes with sterile water and unzipped the rest of the shell (without breaking the membrane). I placed the egg back in the incubator and lo and behold the chick 'hatched' within seconds. However its bum is sticking out a tiny tiny tiny bit and there is what seems like half a drop of blood on it. The chick has smudged the paper towels at the bottom of the incubator with a little tiny bit of blood too. it does seem a tad weaker or more exhausted than the others at this point as well. Should I leave it in the incubator to rest on its own for a bit despite the high humidity? What on earth could this bum thing be and how do I help?! The other chicks are in the brooder all fluffed up, warm and chirping happily away. I just don't know what to do about this poor chicken and would really appreciate any advice or pointers!
