Chick hatched a few minuted ago and the gunk is attached to the shell. Get that that will dry out and fall off. It didn't absorb all of the yolk I think. Has an eraser sized yellow bit at his navel and attached to the gunk. kinda ok with that. What I am really worried about is the thread like piece that is attached to the sack in two places yet somehow wrapped around one leg? To fine to show up in pic. What can I do? will that dry out? should I clip it?
