Hi, My forth hatching, finally successful, after I quit using the LG. So I am still new to this. My one chick that hatched last evening still had something attached to it. I think it is the yolk sack, Not all of it but about the size of half a marble. I let it alone and took the other two chicks out of the incubator this am. I left it in there, some o f the size has decreased, it doesn't seem to be in distress, is standing and sleeping and moving around. Will it be ok? Sher, 2 Bearded Collies, 4 calves, 53 juvenile chicks, 3 just hatched, 7 runner ducklings and 7 Heritage turkey poults.
