Please can somebody answer a couple of questions for me:- 1. Why does my bird bang his beak on the floor, is he having some problem with his beak (seems to do this only when he's playing) and its not very often but it look sore when he's doing it. 2. Why after 3 years is he going for my furniture, particularly my couch which is made with fabric. Is he lacking something. 3. Is is ok for him to take a bath during winter, and in the evening? If i start washing the dishes, he takes it upon himself to go swimming in his water dish, i'm worried he might catch a chill or something.
