One of my Buff Orp hens (3 yr old) has suddenly (within the last 3 days) developed a huge mass above her vent. I have given her calcium tablet and epsom soak. I also tried to help clear the vent out (as it seems to be "plugged" with whitish/yellowish gunk). Now, her vent is bleeding. She has been acting normally up to this point, but her poop has been like egg yolk/whites for 2 days and her bum became VERY dirty. I'm not sure what to do at this point.
I’m sorry, I hope it doesn’t come to euthanizing her. Keep us updated. Perhaps another warm Epsom salt soak would help if she likes them and tolerates them well. If they stress her out, I would steer away from that, though. Maybe something like coconut oil on her vent would help soothe it if it’s raw at all from any injury.
