So it was brought to my attention that my Bantam Roo has a knot in the middle of his chest. It's big and hard. I have noticed that recently he's been sleeping a lot and his color, redness, is fading around his eyes. He stays to himself. He also breathes roughly. His whole body moves as he sits and breathes. Is droppings watery and yellow. I gave him better bread. It firmed the stool yet still it is watery and yellow. I have also given vet RX, in the waterer. It still tends to stay down. He does still Crow strongly, but rarely. Have you seen these symptoms? any helping suggestions / comments ? What's the knot on the breast?
