OMG me too thought my chick had brain tumorWow, phew... then this is normal? YES!![]()
And here I thought that it would have a tumor or something!
Thank you SundownWaterfowl, Thank You, Thank You!
It's crazy how much you think you know about the birds, something always proves you wrong. I've owned silkies for over 7 years and wasn't aware of the vaulted heads! I better come out of my shell more often!
Thanks again SundownWaterfowl!

Pkease can u put my mind at rest and tell me mine is vaulted too.. hes fresh out the incu so hes not done his hairIt is called a "Vault".

I personally prefer the vaulted silkies over the non vaulted.
Here is one of your pictures. It is a very large vault. Nothing to worry about.

Is mine a vault skull too??That's normal. That's called a vaulted skull. Some folks say that it makes the crest larger.
My silkies almost always have a bump on there head they almost seem silly though because they get their heads stuck I also had one drown in a little chick water!Hi Everyone,
This chick just hatched (within the last half hour), it is a Splash Silkie.
Has anyone every had a chick with a large bump on the head hatch before (as shown in photos below)?
Anyone know what it is?
The chick is acting normal, chirping and lifting it's head and trying to look around. No other symptoms to report.
We have had several hatch from this batch of eggs and so far this is the only one with the large lump on it's head.
