I have a 1 year old olive egger hen who's had a dirty bum and weird poo for a couple weeks now and I'm not sure what the cause is. Symptoms: Watery poo that runs down her bum Egg shell in poo, just tiny pieces Her bum is a little red and swollen but I don't feel an egg and it isn't squishy or anything like that. Poor grooming/ feather condition. Bumble foot which I am treating She's acting normal, eating well and drinking. No change in pecking order. Her comb is bright and she still lays eggs at least 5 days a week. Does anyone have any idea why the poo problem all of a sudden? None of the other hens have unusual poo. I've already ruled out worms. What the heck?
