Ok I now have a house chicken for the time being, I don't know what to do but I know I have to try one more time with her. She now has a home in my shower. Sorry to say but it's do or die. Last night after I gave her the anabiotic's I put her up on the roost with the other chickens and this morning I found her laying in the chicken run all by herself and her legs were ice cold and she didn't move and one of her eyes are completely sealed shut. I figure she got kicked out of the henhouse. Since the run is very secure I leave the pop door open all the time. I checked her over thoroughly I even got out a magnifying glass pulled back the feathers on her back, under her wings, her vent area and on the top of her head and I seen no mites lice or anything her skin looks very clean. I will continue to give her the antibiotics twice daily and hope that helps whatever she has going on. Then if she does get better the problem will be acclimating her back to the cold weather because she will be used to the warm bathroom.
OH what a perfect indoor coop! They make chicken diapers ya know. Just sayin'
Seriously though, good luck with her. I am so hoping for the best!
