Thanks for the info. When I said 'about' I meant plu/minus a couple months. Yep, I am aware of the fact that they might choose to go on hunger strike (like my 2 Dumeril's females now). I was just wondering at what size it would be safe to go ahead with breeding them, and if mine, despite the age but considering the size, would
fit the bill.
I have written to Dave Barker from VPI - he just emailed me and said they breed theirs at 9 - 10 pounds, so I guess this solves my question ! 
cheers !
Stan
