One of my chickens has been getting sick with the same symptoms every few months and I’m unable to see a vet. The symptoms she has is lethargy, lack of appetite, gurgling sounds from her stomach, red, swollen and sore vent with discharge. I think this time there’s been small bits of blood? I will post pictures of it. Every time I’ve treated her with these exact symptoms she’s come back to normal. This doesn’t happen to my other chicken and only this one. I’m worried one day it’ll kill her as I have a feeling I’ve diagnosed her wrong. There’s some photos below.
