my BP's curl up too, last night i picked up the male(when they had been curled up) his spurs were fully extended and his vent was slightly opened so i put him back(by that time the female had already started to move) and he started to crawl along her side, i didnt see them breed but i left them alone for the rest of the night after that. also they seem to favor one hide, i thought it was just because it was on the hot side but then i moved it to the cool side and they went back in the same hide. does anyone know what they are doing?
