I have a female bearded (yes, 100% female proven breeder) that has taken up head bobbing and fighting with her male cagemate. There have never been any problems between the two, but in the last few days, she has started bobbing her head and chasing HIM around the cage. So much so that she had to be removed and put by herself to keep from hurting him.
I know that females can become agressive (as in all species), but is it normal for her to take on the attributes of a male? Flaring up, darkening of the beard, extreme head bobbing, etc. If I hadn't witnessed the laying of fertile eggs myself (not to mention the lack of hemipenal bulges), I'd swear she was an aggressive breeder male.
Any ideas or suggestions? I'm baffled. She is a top notch, beautiful breeder. I'd hate to see her unable to produce a second clutch of offspring.
