It all depends as Jeff and Brandon said. Males can be pumped up and bred fairly early, but I wouldn't do that with females. I don't have the experience breeding chondros yet, but I can't imagine rushing into reproduction would be good with a female since she carries the vast majority of the burden. Of my upcoming females, none will be bred before they are four, and with quite a few I'm waiting until they are five, and significantly over 1000 grams.
