Hello, I have a young Sumatra roo that is acting very strange on occasion. About 2 months ago was the first time I saw him do it. he kind of wiggles and falls over and just lays there for a couple minutes and then hops up and walks around like nothing ever happened. I didn't notice him doing it for sometime and now in the last 2 weeks I have seen him do it quite a few times. Very strange behavior. Does anyone know what could be wring with him? Thanks in advance!
