Hi Cowgirl,
When you had an 80/20 female/male ratio when you had the temp at 102F in a still-air incubator, did all the fertile eggs hatch? In other words did the 102F temp cause the male embryos not to hatch?

No, not all of the fertile eggs hatched. Many of them candled well at day 18, and then failed to hatch. And I got about 80:20 female/male ratio. I believe that the unhatched chicks were mostly males. I didn't have the guts to check the genders of the unhatched chicks, but now I wish I had.
