I have just one Serama that hatched out yesterday from one of four eggs that I collected from my birds. He/She appears to have a little difficulty swallowing, and when I was holding him it appears that he has a full crop. That can't be right, he hasn't even started to eat yet. So upon further inspection, he has a perfectly round, marble-sized blister right by where his crop would be. It is almost papery and it appears that it would pop very easily. Does anyone have any idea about this? Thoughts or suggestions? Please help!
