I have a 2 Yr old RIR that is looking pretty bad. Gasping for breath and her comb and wattles are blue. Her belly is swollen and has been for a couple of weeks, but she's been eating and laying, though she's not as active as the others. Today, I found her laying on her side in the egg box. When I disturbed her, she got up and joined the rest of the flock, but I caught her to take a look, and that seemed to drain all her energy. Now she's just sitting on a towel and kind of leaning to her right, gasping. I also noticed she has some rooster damage under one wing - not too bad, Ive seen way worse. I don't have much hope, but this forum has helped me save chickens before. Any thoughts?
