I noticed, especially with cons, (I know you got HRPs) that batches will be mainly male or mainly female, you don't usually get an even mix. I think it might have to do with temperature like in alligators. Anyway, HRPs are pretty easy to sex, so take your time, insist that the guy nets out exactly which one you want, and if you have to, shop around. If your having a hard time sexing, do a search on this site, there have been like ninety threads on this.
