Hi there. We need some help in understanding why 'Billie' our Indian red neck is sicking up on his rattle and then eating it again. He is healthy and not sick he is 3 and 1/2 years now. His rattle is the world to him hes :11: beside himself when we take it out of cage to clean and he also seems to be doing a funny dance head bobbing to the rattle of late too. We brought him last year he came with the rattle, so we've had him 9 months. Does he think its his chick or mate ??? Thanks
