Hi everyone! I'm new to the world of chickens and had no idea what I was getting into when I took on 8 homeless girls who were no longer wanted by their prior owner. I was told they were 6 months old at the time (now 9 months). I have been at my witts end this last week trying to figure out what was wrong with a hen I had. (She just died about a hour ago). She was acting depressed, we had just butchered a rooster that she bonded with and I had thought that was her problem until I noticed everyone picking on her. She wasnt eating or drinking. Her stool was loose and very yellow. I removed her from the coop and placed her in a quiet place away from all the others. Anyhow, I went to go get some antibiotics and a dewormer came back home and she had died. When I picked her up, there was a very strange, fowl yellow substance coming out of her beak. I guess my question now, is...does anyone think the rest of my flock is at risk? I have ordered some DE, (I just learned about this lastnight) and am trying to do everything I possibly can to keep the rest of them safe. Should I bleach all the things that the hen had? The area she was in, etc? What about the coop, she was in there for a good week before I took her out to isolate her. Any help or suggestions greatly appreciated! Thank you for such a wonderful website!
