We have a 9 month old Barred Rock hen who is very docile by nature. She was the bullied hen in our flock so several weeks ago we moved her to a more quiet area with some of our more docile hens. She never really came back to her old self. She stays still and has her neck all curl up into herself. She has now developed a very harsh sounding rasp and gurgling sound. It comes out more when she is stressed or picked up. We have been giving her Neo-chlor (tetracycline based antibiotic) in her water but today she seems to have stopped eating and has runny bright green, almost neon, poop. She just stands still all day with her eyes closed and heavy breathing. I don't want her to suffer but I am willing to wait for antibiotics to work, if anyone can help or has suggestions or may have seen this before. Do I play the wait and see or do we resign the fact we may have to say good bye to Barbie?
