Do you mean "take it away" like take it back to the 'wild?' I doubt it, but maybe if you're going to let it outside as a precaution you can put the top of a cage or something over it, so it can't fly away or anything but it still has the fresh air.

We own a black feathered myna and been in our house it doesn't know how to fly because its not exposed to nature much but today it got let out in the garden is it possible for other mynah birds to take it away!?!?
