My baby Mango seems to be filling out or getting fat. I guess I need to get a scale.
There is something else you can do to help Mango to "stay in shape" .....

.
Flying is the best thing, that's what I have noticed with Marley.
When I got the entire 410 grams of her she couldn't fly. I assume people who had her didn't let her out of the cage and were feeding her seeds.
When I would raise her up in the air and try to encourage her to fly, she would not be able to hold herself in the air and would glide down to the floor, poor thing.
Then she started flapping her wings really hard standing on the top of her cage and holding the cage bars with her feet. She would do it every day for about a week, and only after that she was able to fly to her cage from about 3-4 feet of me standing away from it. I was increasing the distance every day...... and now, oh boy, you should see her maneuvering around my house.....it's a lot of fun to watch her. She knows where her stands usually are in different rooms, so she just takes off and goes from room to room to land on each stand just to exercise sometimes.
I think she lost all this extra weight because of her desire to fly.
Was Mango able to fly wearing his harness? That could be fun, I think.
