My BP's will coil up together and I will come into the room and seperate them a little bit and at the bottom of the coil there tails are matched up exactly one right next to the other. Am I missing the copulation, is the female non-receptive? I have put her to two different males and have seen the same pattern but never have never seen the actual act. I know others have had similiar situations and I just need some feed back. All other BP's breed within a hour of bieng introduced.
