Chick hatched with Bald spot on head

[inquisitivebird]

I just hatched a chick that has a bald spot on its head. It is a Dorking Orpington leghorn cross. Half Dorking. Has anyone seen this before? What is it? Other than the spot the chick seems healthy.

I have hatched 3 that had a bald spot, unfortunately they all died within a couple weeks. I don't know why it happens or what it means.
