There'll be a total of 18 chicks hatching. So a larger batch then I usually do.

Very interesting indeed.That's an interesting experiment! I've never heard of temperature affecting the gender of birds, but I know temperature dependant sex determination is a factor for certain reptiles like crocodilians and some species of lizards and turtles. I believe certain species of fish have this trait as well.
Yes for those animals, but chickens definitely have genetically determined sexes. Males have ZZ sex chromosomes, females have ZW. We know the chromosomes determine sexes because of all the sexlinks that people are breeding: it ONLY works if the chickens inherit certain genes (Z chromosome) different from the father than from the mother. Genes on other chromosomes cannot be used to make color-sexable chicks in this way (examples: blue feather color, lavender, mottling, lacing, Dominant White, recessive white, silkie feathering, frizzling, foot feathers.)That's an interesting experiment!
