Wow. Normal females of breeding weight here are about 200 250 so that is a deal already. But never heard of anyone selling gravid females before unless like me you bought out another breeder.Can't help you on price there but seems sort of sketchy, I would never sell a gravid female I would hold on to her till I got eggs and then sell the babies so you may end up paying on a speculation of 50% mojave in the clutch at whatever amount of eggs she produced in the past.
