I just hatched 17 out of 20 pearl guineas. One is really troubling me...it pip'd last night and he was able to get a large piece of shell and membrane out of his way. He was breathing and making progress with his hatch, but started to foam at the mouth. The white "bubbles/foam" was the sticky albumin. I was able to get some of the foam off, but didn't want to risk helping him out of the shell. (vessels were still evident) Could the chick possibly busted the yolk sac during his wiggling? When I got up this morning, I found the chick still in the egg as he was when I went to bed. The albumin was almost like superglue! He was stuck in his shell and his shell was stuck to the one beside it. Could I have done anything differently? I know that some make it and some don't...but it's always nice to know.
