OK she won't even stand up now, just sit with eyes closed and beak open. I found no mites or egg, and she definitely has lost weight. At this point I'm wondering whether to just put her out of her misery. I just don't want this to drag on for days.
So like a week ago I noticed my americauna hen (3 years old now?) seemed a little less active/kind of stand offish. I just made sure she got food and water and hoped for the best, I've overreacted to things like his before and I couldn't really find anything particularly wrong about her...
