Thanks for the replies...
I agree with the point regarding females. The youngest Ive ever bred a female was at 11.5 months. She was virtually full grown and pacing her cage at the site of males across the room. It was obvious that she was ready .
But I now have a 12.5 month old female waiting for a mate. Shes definitely ready , but the oldest males are born last April, making them about 7- 7.5 months old now. They don't appear to be full sized yet, but do appear ready to breed. My goal is to avoid an infertile clutch , but still trying to push things forward another 4 to 6 weeks.
My female is presently on a small ration feeding schedule of about 3 - 5 2/3 size crix a day with limited supplementation . Hopefully she will hang in another few weeks. I'll start her eating more with more supplementation a few weeks before breeding.
