So tomorrow I plan on getting some more baby chicks and I recently read that some breeds such as silkies have a weird shaped skull that if they get hit in the head even slightly that it can kill them. My question is about these 3 breeds: Ameraucanas, Welsummers, and Golden Laced Wyandottes. Do any of these 3 have that type of skull in which I'm talking about or any problems that I should know about?
