Should be the other way around 3 females to every male. I agree with having double gene males. Makes breeding them more worthwhile. Though it's not a big deal if you don't bc you could breed your own and hold back for the first 4 years. I personally enjoyed breeding them myself. Then you could trade up or do something different when you hatch those first double gene clutches if you choose to do so. Get your females together and get them going. Depending on the ages of the females you have plenty of time to get more females or double gene males.
