I have a broody hen that is hatching eggs. They chicks started slowly working there way out today. Still none hatched but I just went out and found that the one chick that is the closest to being hatched is covered in those little black ants. The chick has broke some of the shell and is still in the membrain but there are a lot of little black ants on it. What do I do? I am new at all of this and am kind of freaking out.
