We had one little silkie baby hatch tonight, but it looks like it hatched early as it's eyes aren't even open (then again, I have zero knowledge as to what a chick should look like), it was under the one broody (there are two in this nest) and still had the bottom half of it's egg attached by the umbilical cord, the other broody pecked it off and the mother broody is stomping all over it and rolling eggs on it while it's still curled up in a ball. Is this normal? Should I leave them alone or start setting up a brooder?
