It was in the winter. I didn't have any other bird that got sick. I had 200 hens at the time and isolated her. Gave her medicated water, but I don't know if she drank. I don't know what was wrong but wished I had just given her an injection. She went into the dumpster ; she did not last 24 hours. Any sign of illness and I inject now. I have only had a rooster get ill since, injected him and he rebounded fast.
