OK - odd question. If your incubator is off temperature a bit, is it likely that more females would hatch than males? We got an unusually high number of female chicks (yay!) and I wondered if it was because my incubator was cooler than recommended (only because I didn't notice the temp had dropped a bit). My husband thinks it's because it caused more eggs to turn into females than males. Is that possible? Can eggs originally be either sex? I guess I thought eggs themselves were either female or male and the sex was determined before the eggs went into the incubator. Any knowledgeable folks out there that can explain the science of eggs? And if temps can cause one sex or another to form?
