i have a b&g approx. 8 years old. yesterday he did something very strange, that i have never seen him do before. he was standing on 1 leg, grabbing the base of his tail with his other leg while make a strange chattering noise (a noise he doesn't usually make.) it almost sounded like a gerbal or something. his tail was also pointing downwards. i went over to check him out and felt his tail to see if he would react in pain. nothing happened at all, he just went back to being normal and he seemed fine. i'm not sure if he's sick or if this is some ritualistic behavior i have never seen. anyone? thanks!
