Onyx has gone downhill further. After yesterday, when she was so excited about treats, I thought she had bounced back. When I came home this evening, she was by herself just sitting on the grass. I went to catch her, and she went in the space under the coop, just standing there, now just sitting with seemingly labored breathing. I cannot reach her there. Earlier today she was just standing by the water bucket. I caught her, and for a brief moment was able to feel her belly, which is out beyond her soft breast bone, and hard. I am fearing this could be a tumor? Have read that there is no curing swollen bellies. Not sure what to do. I have a sinking feeling she'll die soon.
