Good advice as always.It looks like she had the prolapse and others pecked at her vent area. There are missing feathers and another wound to the left of her vent. They can have a prolapse from straining to lay an egg. Give her a human calcium tablet with vitamin d 300-600 mg orally directly into her beak to swallow. Tums can be substituted, just break in half and give the two pieces into the beak. Calcium can help with muscle contraction to retain the prolapse and to help pass an egg. Do you feel an egg? There may or may not be one. Lubricate the vent inside and outside the vent with honey, vaseline, hydrocortisone cream or other mild oil. The prolapse may not go in or stay in for a day or two. The swelling can go down with the honey or some sugar. The discolored area on the outside is fairly normal from drying, and should eventually come off. A daily soak in warm water will help her keep clean and heal.
