I have a poland bantam hen who hasn't been looking too well for a while now, she doesn't move a lot, just stands around looking very lethargic. Doesn't care if you touch her but then again she always liked being given fuss anyway so that doesn't help. She has been kinda quiet like this for a few weeks now. She was out all day in the rain a few days ago and now it looks like she has a cold, she sounds like a bunged up person would every time she breathes, and she sneezes often. What can I do to help her? I don't want to goto the vet because he will charge a lot and he doesn't even know anything about chickens so he will just give her an antibiotic jab (like he always does for everything when I bring a chicken in).
