Can anyone help us. This is a 6 month old Silkie roo. He was fine . Two days ago he starting throwing chest way out with neck way back. Treating for sour crop or impacted, but crop didn't feel bad or inflamed. Trying to find aviary vet. Feeding yogurt, massaging crop. Wondering is it wry neck, but had a chick with that once. Doesn't look like it. No one seems to have any idea. It can sit up straight, but then chest goes way out like a balloon again.
