Well, another chicken down. Culled her this morning as she looked 20x's worse today, and had mucus EVERYWHERE. After culling her, I was able to find the crop (a new thing for me) and it seemed REALLY spongy. When I took a look at her this morning, her eyes were all mattered, mucus coming out of her nose and mouth, horrible raspy breathe, she was breathing so hard, her rear end moved up and down, so I decided that was it. I culled her and have her body in the freezer. I will probably have to wait until after the husband comes home to bring her body to the vet to do a necropsy. Everyone else seemed fine this morning. This the right thing to do??
