Has anyone had quail hatch that appear to have an air bubble on the side of its neck? Out of 21 that hatched in ou last hatch 3 of them have this and it is really weird. Maybe some kind of blister I just don't know. Please help. Will it go away? Will it get bigger? Will it kill my babies? These are coturnix. This was a mixed hatch, but I think they are some of the goldens that are affected.
