what does this refer to? the feathers or the skull itself??
The skull its self. It appears in many large crested birds, and often makes brain injuries very easy.link
Its what breeds with big crests have. They basically have a hole in their skull that exposes the brain and is only covered with a thick layer of soft tissue/cartilage.
If you feel the bump on top of the head of say ---- a polish chick, or SQ bloodline Silkie---- you will notice its not really a solid bump, its a bit squishy.
Thats what makes the crests in big crested breeds so big.
Also, with them having a hole in their skull they are more prone to brain injury due to pecking etc.
Silkies with vaulted skulls are esspecially vulnurable I think, they are too gentle and calm and will not either defend themselfs or get out of the way of a bully(unlike polish which are pretty quick birds).
I think crooked neck syndrome in silkies is caused by brainswelling due to injury if I recall correctly.
