She's a 2008 patternless, trumbower hypo, het albino, het whitesided, het axanthic. I picked her up at the end of last Summer and am not at all surprised she didn't produce. I put the male with her more to get her attuned to my schedule than anything. I'm hoping 1 full cycle here will get her on track but won't be surprised if she takes 2-3 years as I only do a quasi-cooling with the colubrids here. She was an established, breeding adult that now has to adjust to a whole new system; could take a while.
I personally wouldn't pair a pituophis less than 3 years old. Last year my two females were at the 3 year mark and I just managed to get 1 good clutch of 10 eggs. To be fair, I grow my snakes a bit slower than most folks. This year the same two females each laid 18 perfect eggs and one just double clutched for additional 9 pearly whites. It's looking like the other girl is building for a double clutch as well. They really haven't grown a great deal since last year - at least not in comparison to previous years - so I'm thinking 4 is a good age to start producing nice sized, healthy clutches with females.
