I wouldnt recommend it, but if you are going to house multiple beardies. I would do females only. Males and females won't stop breeding, which is bad for the female. Only males would cause fighting. If you choose to house them together, make sure the enclosure is big enough for them to have their own space, have at least 2 basking spots. Lastly makes sure they are just about the same size. I had 2 females once, and the larger one would bite the head of the smaller one and drag her around the enclouse.
