I never successfully incubated for males - a couple 'off' animals made the one major attempt I can recall not worth repeating. Last year I got 2 or 3 females at 80.5F anyway.
Not sure why you'd want a male, since backcrossing is problematic enough to not do it without a very clear genetic goal in mind, one that overrides the inbreeding issues. Best to get an unrelated male with the looks/genetics you want.
