Hi! I was wondering if anyone could help me. My isa brown hen stopped laying eggs about four weeks ago. She has a very enlarged vent that is kind of hard and she has runny droppings. One of our other hens had the same thing this winter and passed away She still eats and drinks but she stands around and it looks painful to poop. We have been giving her a bath in warm water and Epsom salt and vitamin water. She free ranges almost every day, her bedding is straw and she eats laying hen powdered food. Any ideas what this could be? Possible treatments?
