I have a 4 year-old hen who has been lethargic for a few days. Last night, I noticed her vent area was balding and another chicken was pecking at it. Assuming it was egg-binding, I've been giving her epsom salt baths and feeding her calcium in a water dropper (Rolaids dissolved in water). When I go into her vent with a gloved & lubricated finger, I don't feel any mass. The entrance to her ovarian duct seems OK. Now, I'm wondering if it's vent gleet. There is a small trickle of white fecal matter that seems persistent. The pic below is a bit blurry. The redness is because she's just come out of the warm bath. Can anyone help with a diagnosis?
