We have new hamshire reds.. and they have all been pretty healthy for the most part (they are almost a year old).. this is our first chicken experience, so we are new at this... A few weeks ago one of the chickens started acting odd - we also had a broken egg , but the shell was mostly missing - just a yolk.. she seemed to be swollen on the hind end and trying to pass something.. She had loose stools that got all over her backside and waddled around .. now she wont' even get up - her wings are spread out.. I think she is losing her eyesight as she looks at everything odd. and bit at me trying to get a treat (with a weak bite).. her comb is purple and pale.... We bathed her in warm water a few days ago, trimmed the heavy poppy feathers thinking it could relieve some of her discomfort... but to no avail. She looks really puffy and swollen all over... what do yall think happened (no worms that I could see in her stool btw, and no blood).... and now what - I think she is miserable.. is it time to put her out of her misery or could she turn around?? We have doctored a few injured (from a coyote) chickens and one internal layer back to health - the internal layer was then sterile.. but happy! I just want to do what's best for her... help!
