first of all, if youre planning on getting an adult female, expect to pay about $175 at the very least, unless you are getting a special deal from someone you know. the most cost-worthy way of obtaining a female is yes, buying them as babies or juvies. theres the chance youll end up with another male, but thats just the way it goes. the bright side is you could buy about 4 babies at the same price youd pay for an adult female. there is no one for sure that can produce all-female babies, and as far as i know, there isnt anyone who has babies that come out predominantly female. your best chances of getting a youngster thatll turn out female are if you look for generally smaller cloacal spurs (those lil white spikes near the base of the tail), since the hemipenal bulge doesnt come until theyre a few months old or so, and the preanal pores develop around the same time as the bulge (not to mention youd still need a magnifying glass to see them). good luck in your search!
