I have been caring for my 2yr hen for 3weeks now. Started with worming, no change. Gave kefir, slight change and was hopeful. She has had her comb go from normal to pale, back to red almost to dark, then now pale. Always limp though. Her droppings consistantly green, loose with cottage cheese like matter. She passed a rather large mass thought to be from infection. Seemed to rally then get weak again. Gave her vitamins & treated her bottom as it was red from all these loose droppings. She has lost so much weight. Several times we would have put her out if her misery but she seemed to always try to rally. Also had to treat her for bumblefoot!Forgot about that! Seemed to be better and I was so hopeful. Now she barely eats. I wondered if I should treat for worms again as I am out of ideas. Worried she's to weak for that but just don't kniw anymore. Have read so much, thrush, worms, etc.....just dont know. She's all bone, but still coo's when andI talk to her. Honestly I don't know how she is still alive and I don't want to give up but 3weeks? Is that even normal? Never had a sick bird before. Please advice.....anyone?!
