Head bump in chick?

[Ponyfeather]

I don't know what is up but the sulk shape of this chick I am helping raise seems to have a bony bump on the top of her head? Is this normal? She is perfectly healthy other than this strange anomaly? She just turned two weeks old.

Could you post a pic of the said chick? What breed is she? I raise polish and they have vaulted skull, when they hatch they have like a bump on their head. Here is a pic ~

Silkies also have vaulted skulls.

Thank you, she is a mutt. But she looked just like those chicks with vaulted skulls you posted close up. But dad is part silky I think now, since he has feathered feet. At first I thought cochin banty, but now knowing Topaz has a head bump and mom is of a breed that don't normally have vaulted skulls.

Glad to know what is going on. I was worried she's my baby. Sorry bad photo but only one I have that shows her 'bump'
