I just bought an entire quail set-up with 3 pens and ~40 birds. One has been acting sickly. It’s doing better now. I noticed it was lethargic last night. It’s a 4-week old coturnix quail. It was puffed up and was incredibly calm (didn’t try to escape me). I also noticed it was very skinny so isolated it and offered it water and a raw egg mixed in with its regular feed. It has incredibly watery droppings. I also noticed some of my other quail seem to have swollen areas around their eyes.
