My budgie's leg is hurt and she can't perch. What can I do at home?

Ouch! That does sound like she's injured her foot. Until you can get to the vet, providing some low, flat perches that are easier to stand on (like a platform rather than having to curl her toes around it) and food and water dishes she can easily climb in and out of may help her relax the foot a bit and maintain her balance easier. Keeping her warm and preventing her from picking at or chewing on the foot can also help. If she's housed with other birds, moving her to a hospital cage to avoid being picked on is also a good idea.

Unfortunately Pearl is going to need to be seen by a doctor, and very soon. Budgies can get dehydrated very quickly. Be sure to monitor as closely as possible of any changes and let your doctor know as soon as you can.

If the leg is currently broken, it needs to be seen by a veterinarian right away as breaks in bird bones can lead to serious infection. If it was broken or deformed in the past but now healed, there may not be much that can be done for it, but a vet can still take a look. Otherwise, changing Parrot's environment so it is easier for him to perch, get around, get into and out of food and water dishes, etc may help.

It is best to move Robin to a separate hospital cage to allow the foot to begin to heal without being picked on by other birds. Providing low, flat perches or no perches at all along with shallow easy to access food and water dishes may help. If there is a visible wound or break, treating the wound or seeking veterinary care to have any broken legs treated is best. If the swelling continues, worsens, or other symptoms of illness appear, seeking vet help ASAP is needed.

Inability to perch and balance are very concerning signs, and seeking vet care is needed to find the problem. Even if the vets in your area do not specialize in birds, seeing if one can still take a look is best. Injury to the legs, illness, malnutrition, stroke and a myriad of other issues can cause balance and perching issues, and they require medical care in person to treat. At home you can try to offer low, flat perches and food and water in shallow dishes that are easy to get in and out of, however seeking veterinary care in person is needed to get Bluey feeling better.

Unfortunately, if the leg has turned black and isn't being used, it is possible it is very badly injured, infected, etc and may need to be amputated. Even if you don't have a bird-specific vet in your area, you will want to see if any vets nearby will at least look at the leg and prescribe medication/potential amputation as needed. At home, keeping her eating, drinking, and preventing her from picking at the leg can help, but if it is is causing her lots of pain or seems to be worsening rapidly, veterinary care in person is needed ASAP.

Unfortunately, without knowing what is wrong with him there aren't really any remedies that can be given unless you see a visible wound or injury. It's possible he may have been injured by flying into an object, or even having a stroke or other underlying issue that caused it. If you can't get to the vet, keeping Tulip in a separated hospital cage with easy access to food and water may help, as well as using only low, wide perches to make it easier for him to stand and shortening any falls he may have. If you can't afford care, this site may also help provide you with some ideas to make it more affordable, so that Tulip can get the care he needs: (some of these may be US only, however there should be equivalent programs in Canada) http://www.humanesociety.org/animals/resources/tips/trouble_affording_veterinary_care.html
