Once you have been keeping bearded dragons as pets for a while, you may want to take the next step of owning these beautiful reptiles by breeding them. Obviously to begin breeding you need a healthy adult pair of dragons. Bearded dragons can be kept singly or in sexual pairs, but also in breeding groups consisting of one male and two or more females. More than one male should not be kept in the same enclosure as fighting may occur, particularly during the mating season. To determine sex, hold the dragon in the palm of your hand with its tail facing you, supporting its body and front limbs. Gently lift the tail up over the back at approximately a 90 degree angle, being careful not to bend the tail too far or too roughly, as the vertebra at the base of the tail may be at risk of being broken. Upon examining the area just above the ventral opening, if your dragon is male, hemipenal bulges can be seen on each side of the tail, causing an indentation in the centre of the tail between the two hemipenes. Males also often have enlarged preanal and femoral pores. On a female the hemipenal bulges are absent, thus causing the area above the vent to protrude slightly, or not at all. On smaller dragons it may be necessary to gently roll the tail between your fingers and thumb to expose the hemipenal bulges of a male. Some breeders use hemipenal eversion as a form of sexing dragons, where they push at the dragon?s cloacal area in an attempt to evert the male sex organs, however this method, along with probing?, can seriously damage the dragon and is not recommended. Successful breeding usually follows a short rest period, known as brumation. Brumation is a natural period of semi-dormancy. It differs from hibernation, where an animal undergoes more extreme physiological changes. Brumation involves gradually dropping the temperatures of the enclosure and decreasing day light hours to mimic a natural photoperiod. Although most bearded dragons will breed without any type of brumation period, low fertility rates have been reported
