I don't have an avian vet in my area. My duck is not well and I'm not sure if there is something I can do to help her. Her nose is clear and she's eating and drinking. But she has no energy, sits with her eyes closed, not walking well, her feathers are fluffed and thinning, losing weight, prone to prolapse, vent area is dirty, poop is white and watery, and she is no longer laying eggs. I put my two ducks in a coop at night, but during the day, they free range and swim in our pond. She's not the friendliest gal right now either. I'm worried she may have an infection and it will be beyond my ability to help her. Any suggestions or advice?
