I have a hen that I recently figured out must have been eggbound for about a month+. Today, I found a piece about 1" x 3" of hard leathery dried up yolk, with a little bit of manure coating it. When I opened it up, there was pink tissue inside. I ASSUME it's from this certain hen, but am not sure. I'm guessing this is an advanced case of eggbound, and she should be put down. But I wanted to check first. The hen (a BR) waddles around, often with her tail feathers dragging the ground. Her lower abdomen is very swollen. I gently felt all over it and felt nothing shaped like an egg. What should I do???
