no, we haven't actually witnessed anything. we actually have three, and we had them probed and were told 2 were male and 1 was female. the female (the one they said was female) is the oldest, about 3 years and 2 months, the other two (that we were told were male) are just under 3 years old. We are confused! had no idea what to look for or anything, thought they wouldn't breed for another year or two still. but no, we haven't seen one chasing the other or anything like that. Anybody know of any ways to check sex that can help us out here?
