I bred a pair 2 consecutive years in a row a few years back. All clutches took about 42-45 days to hatch (from memory - memory shakey but I'm confident). All healthy babies.
About 30.5 / 31 I think. I can't remember exactly. These were animals I got from Rick Walker. The female was gravid when he sent her to me, then laid another clutch that season and 2 clutches the following season.
