90 degrees is the right temp for males(88-90 degrees). I do have one question, is that the temp in the incubator or in the container you are going to put the eggs in? Because I have noticed over the years that the temp in the container can some time be a few degrees lower the the temp in the incubator. I have also noticed noticed that the incubation medium in my male incubator will dry up faster than in my female incubator. So keep an eye on the temps in your container, the humidity(around 60-80%), and the wetness of your incubation medium(just wet enough theft it clumps up when squeazed and no water drips out). Hope this helps and good luck with your first egg.
