My beardie is almost 3. Her beard ALWAYS turns black...she does the head bopping and she even does push-ups. I previously worked in a vet office so i keep in touch with the reptile specialist there. He's very good. He said the
black beard and head bopping AND push-ups are normal. The
black beard means they have reached puberty and are starting to get "excited." The head bopping and push ups are a form of communication. Possibloy to attract a mate....or something along those lines. I have 2 cats and they play with my beardie. Whenever they come towards her...she has recently begun to get a black bear all of a sudden, she will bob her head like crazy, then take off running like a maniac. It worried me at first but apparently its normal. I dont know any other beardie owners so i can only go off of what my vet says. But she just laid eggs for the first time this weekend and is sick now. Maybe yours is a female about to lay eggs too? Who knows...good luck. If you have questions, let me know.
