A couple days ago I lost an older hen of mine. She had circulation problems, due to old age or something else. Yesterday, I noticed one of my newest hens (olive egger) had a watery eye, like she maybe had something in it. Today, her upper eyelid is a tad swollen and running again. She isn't sneezing or making any noises out of her norm. She is acting completely normal. Do I need to be worried about this? I read about respiratory issues, but it doesn't seem like what is described. She always opens her mouth to breathe and clucks like crazy when it's hot. I don't know if I am being paranoid due to the recent death or if this warrants some antibiotics or something.
