I just adopted a copper marans hen who won't put weight on her left leg. The previous owner didn't take her to a vet and thought the bad leg could be due to an infestation of scaly leg mites which she says she cured. They kept her in isolation for three weeks but the leg didn't get better. When I got her home I examined her thoroughly. She seems underweight, I can easily feel her keel bone when I pick her up. Her comb is slightly faded at the back, and her "ear lobes" are also pale. Her wattles and the front part of her comb are red. There is no sign of scaly mites on her legs. I inspected right up to her "knees" (where feathers grow). One of her feet looks slightly thicker than the other. Her feet are not hot and are the same temperature. I felt the toes, feet and up the legs as far as the hip and found no swellings or signs of a fracture. I bent the joints and pressed the bottom of her left foot, but she did not flinch or make any sound when I examined her. Both legs and feet have the same range of motion. I examined her feathers and skin and could see no sign of lice, mites or any other parasite. I do have Ivermectin (oral solution) and Worm-X as well as a residual permethrin external parasite spray. I haven't treated her with these, but I plan to in a week or two. Her breathing is normal with no sounds. She eats well. Her poop appears normal. She is alert and makes "bawwwwwwwk" sounds when I enter the room and while I'm near her. She spends the majority of her time lying down on her belly or side, next to her food dish (she places herself there). She can get up and hops on one leg to move around. So now the questions: How can I tell if she's in pain? Do they make a sound? Are there other signs I should look for? I know most animals hide their pain. Is there any natural supplement or food I could give her that would help? What's the best way to get their weight up? Right now I'm feeding her layer pellets from her previous owner, and a concoction I give to sick or stressed birds. It contains shredded romaine lettuce (or other greens), Perle Morbide (a supplement that mimics the nutrition of sprouted seeds), bee pollen (vitamins and Omega 3), boiled quail egg with shell or fish meal, and trace mineral powder. I also add an herbal supplement called Guardian Angel which helps stressed and ill birds. I'm giving her pigeon grit which contains oyster shell, granite chips, kelp, and a vitamin supplement. She LOVES the green concoction. Do they need salt, as pigeons do? I noticed her claws are quite long, probably from not walking or scratching. Is it a good idea to trim them? I keep a worm composter with "red wigglers" - are they safe to feed to a chicken? Are they nutritious for chickens? Is it a good idea for me to pick her up and move her a bit every day, to encourage her to stand and try to walk? Or should I wait a while first?
