First time I have seen this..... One side of my hens face is swollen. Other side is perfectly normal. It's been like that for a couple days. Her poo is runny, but normal color. Shes a little slower, but still scratching around and hanging with the flock. She seems to have lost a little weight, so maybe it hurts her to eat?? other notes ... she eats layer pellets, we live in Central Florida so nice weather in 70s. They range during the day, and have coop for the night time. Any idea what it is, and what I can do to help her? Thanks, Oh, and she sounds a little phlemy. Not much.
