Change in behavior
I am concerned because my cockatiel just recently started holding his poop overnight. He waits until the morning when we get him out of his cage and then has an enormous poop right when he gets out. There is absolutely no poop in his cage. I read on quite a few bird forums that a lot of birds do this, my concern is that it is a new behavior. We have had him for 8 years and he just started doing this about a week and a half ago. Appetite and all other behavior is normal. Any idea what would cause this?
