First off, I love this site! It has helped me build my coop from recycled materials, learn (what I thought was) lots about keeping layers....and the forums have been so helpful! I got my first 5 hens from a a couple who were down sizing their flocks. Didn't know what I know now! anyhow, one of the girls from the get-go seemed to be weak.....I have had them now 3 weeks...and this one little lady has been in quarantine for a week. I noticed after one week of having her her comb was really pale and she wasn't thriving as the others were. She looked like she had a cold in her eye, goop on her nare.....after a few more days she started staying in the roost area, on the floor. I gave her special care taking mash, liquids etc to her. But after a few days of that (one week ago) I decided to put her in a large dog cage and bring her inside so I could care for her better....the coop has a penned in run and a two story coop not great for nursing sick girls. Anyhow, I got some antibiotics for her, made sure she was clean, and basically kept a very close eye on her. Her eye/sinus area on the one side blew up like a balloon, and I thought I was going to lose her, but then, it cleared right up. She was eating really well, drinking lots....and then I noticed the #$%#$ mites! So began the treatment of those....yesterday, I was thinking she would be ready to go back to the coop with the others as her face looked great, eyes clear (although skin saggy a bit after all the swelling).....then this morning, her other eye swelled up! She has not been scratching at her eye(s), has not been sneezing, coughing or showing other sickly signs. I read about the eye worms, the other diseases she may or may not have.... Today I did take her outside in the cage to let her get some real air...it has been so rainy here for 2 weeks. The other girls look amazing! When I got them, they were kind of raggy looking. But the girls in the runn/coop have gorgeous looking combs and great sleek looking feathers. Because it was so rainy and mucky out, after a week or so of letting the grass go with the girls, I decided to add about 6 inches of river sand to the run, and now their legs and feet look great. The coop is clean and dry and gets de-pooped quite often. So, my question, when can I let sicky back in with the others? I did not give antibiotics to the others, just to her. Today is day 8 on them. I didn't want to give them to the others or risk her getting hurt by the others. Ideas? Thank you!
