I have three '09 males (mojave, het albino & spider), all born in early/mid July of this year - putting them at around 5 months old right now. Two of them are still pretty small, but Julius the mojave is growing seriously fast... from 93 to 437g in the three months I've had him.

When I started breeding Toby, he was just at 500g @ around 6-7 months old, and started locking with the girls immediately. So should I give Julius a go this season? Both of my adult females are probably building follicles as we speak (one is looking suspiciously pre-ovulation), so it's now or never! Whaddya think? Does age matter with the males, or is size enough? And how young/small have you all bred your males?
