After reading the prior 2 posts, I'm unclear how exactly a hut could harm a parrot (assuming their talking about the cozy little fabric kinds that tie to the sides of the cage). If your bird is damaging it's feathers because he backs into the hut, the logical thing would be to move the hut (and possibly branch) to a roomier location in the cage. I will say, those "fluffy" kinds could pose a hazard since the bird could rip out and eat or inhale the fluff, but the cotton fabric kind have nothing remotely dangerous about them. I actually made Kiwi his hut (I'm a seamstress), and he loves snuggling in it at night. I used regular cotton fabric, and fully lined it so I could safely use batting inside for insulation. When I wash it once a week, I inspect it for chewing damage (which he hasn't ever done).
