Any Advise

Hi everyone! I am new to the forum. My family has decided to take in a Quaker that a family no longer wants. We are new to any kind of bird and I am trying to learn all I can about it. Any advise would be greatly appreciated. Thank you!

Take it very slowly.
Don't ask it for anything the bird doesn't want to do.
Give it a lot of out of cage time and don't clip it (Quakers will start plucking otherwise).
Give it a lot of veggies, fruits and leafy greens (they are great eaters).
Take it to an avian vet for a complete physical evaluation and have it DNA'd if it had not already been done by the previous owner.
Keep it to a strict natural daylight schedule with full exposure to dawn and dusk.
DO NOT overstimulate! Quakers are very nippy birds and will bite hard when overstimulated.
Give it lots of toys (they are busy little things).

Thank you very much for the advise. I am really nervous, but excited.

Hi everyone, I am new to this also. I adopted 2 quakers from an abused environment. I have had them for about 3 months. When I first got them they had hardly any feathers. I have been feeding them Higgins Parrot food and giving them lots of fruits and veggies. They are covered in grey down feathers. They are both very ill natured. I have been working with them and one is beginning to let me approach her without biting, she just trys to nibble. The other one tries to attack me. I have had to separate them because of them plucking each other. I thought I had them out of the plucking but I have noticed today the one that was really looking good and almost covered in feathers has started back stripping there feathers. Does anyone have any advice to give me. I was told when I purchased them they were about 12 to 15 years old. I really thought I could nurse them back to health but now I am beginning to wonder....Is there anything I can do to prevent them from picking at themselves?? Since these birds are up in age will they ever look healthy again. I really believe they were used as breeders but I don't know for sure. I was told they were both females. Any advice will be appreciated.
