The crossover temperature seems to average 86 F. There are a couple new books out that adresses this issue extensively.

I don't think it is a cold hard fact that the crossover temperature can be a precise temperature.

As to patterns... I had one leopard that laid eggs that hatched in an average of 150 days and another that laid eggs that hatched in an average of 90 days. There does seem to be some consistancy but as I say in biology there are no givens.

>>.. I think "no pattern" is the point Ed. The females all have 3-4 clutches out of the way and the males are now a year older.. new incubators and lower temperatures. In this group.. four females laid their eggs the same WEEK! There should be a consistent "pipping" going on soon.

>>Q.. ANYBODY.. WILL 82-84 F TEMPS YIELD MALES.. FEMALES OR MIX???
