cresteds are bred pretty much year round, depending on where you look. some people give their breeders a rest in the winter and start breeding again in the early spring, but they are not seasonal breeders if their temps are kept steady so many people take advantage of this and breed whenever their pairs are ready.

an experienced breeder can usually tell the sex of a juvie crested by the time it is 3-4 months old by using a jewelers' loupe to look for preanal pores. if you buy from someone who is reputable and good at sexing cresteds this way you can be pretty much guaranteed to get females.
