Well, so far, 4 chicks have hatched and another 4 eggs have pipped. It's almost day 23 and I guess the "popcorn" like activity has begun. When the first chick hatched I started to get really worried. One of it's legs looks slightly deformed. I have at least one curled toe and it came out of it's egg all wet and sticky. It has dried half fluffy and half crusty. It also had a slightly bloody navel and it took a while for the rest of what I'm assuming was the umbilical cord to fall off. All the of the other chicks that have hatched have been fine. I hope this other one will be too. Does anyone know what could cause this? Is it just a low temp or something else?
