Need Advice quickly. Found a budgie.?

My budgies always put their weight on one foot. Its normal for me. I think the best thing to do is to observe if he ever puts that other leg down. Let him get used to your other birds and then let him join them in the cage. (usually when I get a new bird I let him in the cage right away. I have a room upstairs with two cages with its doors always open. We let them fly around freely and can see them from downstairs. They are comfortable with windows and don't fly into them. But don't take any chances! I also think you should put flyers around your neighborhood If you think it may belong to somebody because an owner with a lost budgie may be very worried! Good Luck!
