This morning when I fed the chickens one of them stayed up on the roost and wouldn't come down. When I came home tonight I found her dead on the coop floor. She was a year old and showed no signs the day before of anything wrong. After inspection I found some blood in her mouth and her vent looked red, but I felt no mass near it (egg-bound etc). I couldn't find any other signs of problems.
I had treated them with Wazine a few days ago after I found worms in another hens poop. They have since been eating and behaving as usual. Egg-laying has decreased in the past few days.
What went wrong? What can I do to prevent this from happening to the other birds?
