A friend of mine has a pair of cresteds that are about a year and a half old, however they dont look it. They have been housed together for the past 6 months, but have shown no sign of mating apart from the female nipping the male on the tail. So...what happens if they breed "underweight". I am not planning on it, but am curious as to what the danger is. Also, can one raise a juvie pair together and just let them do their thing whenever? Thanks!!
