Your male seems like hes on the younger side too. That sometimes will have an effect when it comes to breeding. Seems like the problem lies with your male. The male I bred to my female late in the season this year was the same age as her. No problems and expecting eggs to drop any day now.
Also, you are kind of going against the grain in trying to breed in the off season. Some ppl can breed out of season, but the success storys I heard about they were from full adults males averaging in the good 1400-1800 gram range. I wouldn't bother with trying to breed in the off season and just wait till Nov. You will have much better luck and the odds more in your favor.
