Male goes inside nest and breaks eggs.

This silly guy is literally breaking his own eggs. He goes inside the nest when the female isn't inside and pecks them, then he eats them. The eggs are fertile. Should I separate him?

If you separate him, then you are not going to be able to breed. Is that what you want? If you leave him in, you are still not going to have any chicks hatch. If breeding is what you want, I consider getting another male for the hen. This one is not going to work out. Often with the hens, if they start breaking eggs and eating them, that’s what they continue to do, and are considered not worth risking trying to breed from. Maybe the males are the same.

What an odd behaviour for a male, I'd only heard of hens doing this before.
