Hi David,
I certainly hope to see you posting hatchling pics here soon, it is certainly worth the effort.
The pair I bred this year were both hatched in 2002, making them just 3 years old about now. The female is a particularly hearty feeder and reached good mature size early I feel. The male didn't arrive here until very early this year, just in time for breeding actually, but he has obviously been a good feeder as well although he is considerably smaller than the female. At 2 years going into their third year they can be successful as long as the female is physically big enough. This clutch totaled 14 eggs, with 8 eventually hatching.
Evidence shows that age isn't as critical as physical size and overall health. Personally my opinion is that breeding them young may be somewhat less productive that first season, and in that regard it may be better to wait until they are 3 going on 4. However, I also understand that many very experienced breeders don't feel that breeding at a younger age adversely affects the female in any way... meaning no harm done with regard to her health, longevity and productivity within her lifetime.
It's really a matter of personal preference. If your female reaches 2 going on 3, she is healthy, what you feel is a good young adult size and you are chomping at the bit to make babies like I was this year... I say go for it and have a great experience!
