Found injured parakeet

Question
Thanks so much for your wonderful suggestions.  I will give them a try.  Now I'd like to know what you suggest about trying to train her.  We would love for her to sit on our finger and be able to fly in our home but I don't know how we can make this happen.  With her foot the way it is she can't grab onto it.  She is getting a little shy about coming to my finger when I put it near the cage.  She flaps her wings and flies in her cage.  My son holds her while we change hr cage liner and she gets to the point she wants let go. (can't say I blame her)  We just want to do what is best for her.  She has such a lovely chirping voice.  Thanks for any suggestions again.

We found an injured parakeet in our back yard.  Our neighbor gave us a  cage and food.  The one foot appears deformed or injured.  It's claws (toes) are twisted-like.  It is using the other foot now which it wasn't when we brought her in.  She flies in her cage and is eating and pooping well and chirping up a storm.  She is unable to sit on a perch because of the injured foot.  Is there anything you can recommend we do for her foot?  My husband doesn't want another vet bill since we already have a dog and cat!    She seems very happy with us so far and it's been almost 2 weeks and we are happy to have her as an addition to our family.  Thanks for any suggestions.

Hello Sally! Glad to hear you gave a little parrot a wonderful home! I totally understand your reasoning for the vet. It can be VERY expensive. I went in with my grey for a check up and it turned out he had a vitamin A defficeincy (which the vet was surprised because he had a good diet) and i walked out $320 less. Theres plenty you can still do for your keet to make her more comfortable. Instead of newspaper or corn cobs (what ever you may be using) use small animal bedding. This will provide her with comfort as she walks around on the bottom, also it will provide a cusiony surface if she happens to fall. Wooden perches can be slippery and uncomfortable. Get a large wide branch from outside or buy a pedi-perch that has good grip and is wide. Place the wide perches at the very bottom of her cage. If she wants to, she can climb up onto them and rest with out having to balence on one foot. And for hamsters/gerbils, ferrets, you will find cage corners (they are triangles that are wire). Place a cage corner on the top of her cage that way she doesnt have to perch but can still lay on it. Since shes eating great her droppings seem normal and she is active, its a very good sign that shes healthy and does not have an infection. Theres nothing much you can do for her actual foot but by customizing her cage this will make her life easier. good luck!

Taming a keet that hasnt had human contact can be difficult. The first part of handling is trust. By giving her food talking to her, offering treats from your hand, and cleaning her cage she will get used to you quickly. since she cant land very well i suggest clipping her wings that way she can spend some time out side the cage which will strengthen your bond. The wings will grow back eventully and this will prevent an accedent of flying into windows or falling behind something. If shes not used to perching on your finger gently wrap her in your shirt or cloth and take her with you somewhere (like on the computer have her sit in your lap with your hand lightly over her) or at the dinner table and offer her bits of your food. She will get used to you much faster and soon may feel comfortable enough to perch on your hand. dont rush the process though, frusteration can lead to an angry owner and a scared bird. By letting her fly on the ground, if she needs help in a tight spot, you will be there to pick her up to safty. By doing this often she will see your hand as a way of getting somwhere and will eventully jump up to your hand to be carried. Dont skip a day of handling. It makes a big impact on your relationship with the keet. Otherwise you and your son are doing great!
