Do I need to cut feathers to cut the broken chest parrot?

The crimson parrot needs to cut feathers, but only cut off feathers.Cutting off the bird's flying feather can play a role in restricting the flight and ensure that it can't fly too high, so that even if it is flying away, it can be caught.If it is cut too much, it may cause the birds to be injured and bleed, which is very unfavorable to its health.In addition, shearing feathers must be seen once a year, because they will change new feathers every year.
