We've got a BBB turkey at the farm I work at, about 4 months old, and the top of its head, just around the skull, looks as though it's filled with fluid, it wobbles a little when the bird walks around. I can get a pic tomorrow but thought I'd see if anyone had seen this before. It is not swollen head syndrome, as it's just above the skull, like it's wearing a helmet- the face looks normal. Turkey acts perfectly normal, it is a bit smaller than most of the others though. Any thoughts?
