My adult breeders are quite large, with the female being 6-7ft and very heavy. The male is significantly smaller, likely around 5ft or so, and not nearly as heavy.
Do you think this is what I should expect from a nearly 5 footer?
Difficult to say. Generally, female snakes seem to produce larger clutches if they are several years old and fairly large (not overweight!), and have not been bred before. Of course, this also depends in part on the male.
