Perky, bright, eats and drinks - looks fine until you check out the vent area. Some blood, very small clots, the rest is a clear, mucus like, sticky, nasty discharge. No smell, vent feathers a MESS, other chickens interested in pecking her there. Hen stays close to me. Currently, she is in the house in a dog crate on hay. She eats, sits, drinks. I've medicated the water with Sulmet. WHAT NOW?? No eggs today - which is okay. Any thoughts??? This happend very quickly - I immediately brought her into the house.
