Ok so this little chick hatched a day early. This is hanging out of his butt I have read that it can go inside of them, but this is large!! This is what the inside of the incubator looked like when I found him. I am guessing there were 2 yolks??? Should I tie this off with a string so that it dies and falls off?? I read you can do that on a thread here... But I am scared to hurt him. Please HELP!!
