About 10 days ago, I got a humane society hen. I put her in an isolation cage, and have been careful to sanitize my hands after each contact. She is NOT sick so far. However, 3 days ago I noticed a hen with some nasal discharge. I didn't think about it because I had just stirred up a bit of dust in the coop while raking out old hay and putting down fresh. 2 days ago I saw that 4 of my hens had swollen eyes and were breathing 'gurgly'. I immediately dosed the water with duramycin. I had to go away with my son to a scouting camp out last night. They were dosed with meds while I was gone. Today their eyes are hardly swollen at all, but their breathing is still 'gurgly', and they have nasal discharge. 1. What do they have? Am I treating with the right medication? 2. Before I got the humane society hen, I got an EE at a swap. I did not realize about the quarantine thing until I asked some questions here. That has been about 2 weeks. Did the EE bring it in? 3. Are they going to make it? Thanks for the help, in advance.
