Pierson, I have no experience with breeding mole kings but with prairies I would condider that too small. The prairies here lay huge eggs and have small clutches. The before and after is fairly remarkable with a gravid female. The females that I have bred have been more along 3' in total length and usually have laid either 7 or 8 eggs. After laying they look horrible! The babies hatch out after a fairly short incubation period of 50 to 55 days at size of 10" or so and are very robust and often accept pink mice before their first shed. A friend of mine that lives in N.C. has told me that the mole kings he has worked with from that locale were tiny when first hatched, so there is a good chance that a different set of parameters would come in to play with what I have seen and what is the norm for snakes in other parts of their range.
