Hi, I found the thread and it doesn't look good for the little one but luckily no other eggs are due to hatch for a couple of days so hopefully that will give him enough time in the bator to maybe absorb the rest of the mess. He is really active right now and other than the bulge off the back end he is acting like the other chicks that hatched a couple of days before him. sure hope he pulls through.I haven't been through what you are describing yet but I believe I saw that thread too and they separated the chick to keep others from pecking on him and to see if he'll absorb it. If I remember correctly the chick didn't make it but I wish you luck. I'll be crossing my fingers for you!
thanks
