Why is my quail sick, limping, can't walk, and has broken feathers?

I'm sorry to hear this! It sounds like this is likely related to the laceration, it could be that she is painful/swollen which is making her walk oddly. However there could potentially has been some damage to the nerves that run into the legs. If she is eating well and otherwise bright I would give her a day or so with minimal stress to see if she improves. If however, you feel that she is deteriorating or not improving I would take her to a vet as she may need some antinflammatory medication.

Your quail has developed a touch of pododermatitis which is essentially infection and swelling of the soft parts of the feet. It can occur due to standing in dirty areas, uneven areas or narrow perches. I would check your housing is appropriate and clean and also get some antibiotics to help treat the feet. If you contact a vet they may be able to prescribe you something to pick up, or may request to see the quail first.

Poor Turri! It sounds as if the injured toe/foot is causing him some distress and pain which could be why he is showing other symptoms of illness. If he is limping and also acting ill, it would be best to bring him to a vet ASAP so that the foot can be examined and treated, and any other underlying conditions ruled out to help get him feeling better. Until you can get to your vet, keeping him warm, with low, flat perches that are easy to stand on and food and water dishes that can easily be climbed in and out of may help make him more comfortable.

Bumblefoot is very common in these little guys unfortunately, and there is no way to know for sure without seeing Puff. This would be my first guess. He really needs to be examined by a veterinarian, and likely needs to be on antibiotics and potentially a pain medication like Metacam. Hope that helps!

Feathers not growing back in properly can be due to a number of things including illness, nutritional issues, metabolic diseases, parasites, infections and more. If you cannot find the cause of your bird's feather loss and balding, it would be best to have her examined by a local avian vet so they can check for any of these common issues and get her feeling better. Making sure she is on a balanced diet and is treated for any parasites such as mites (most pet stores carry a spray for this) may help, however if the problem continues vet care is needed.

It's possible your hen may have an injury to the leg such as a sprain or break, or even a potential nutrient deficiency causing weakness. If the leg isn't improving on its own, seeking veterinary care to have it looked at by a vet is best. They may be able to figure out the issue or create a brace while the leg heals to make sure it stays in the proper position.

Thanks for reaching out about Chicky and including photos. A physical examination must be made to determine which of these it is, and each will require a different treatment plan. There are some infectious diseases that can cause this also like bacterial infections or Mycoplasma gallinacium. Provide good diet and husbandry, especially heat support. Good luck.
