By having a controlled temperature change throughout the year, do you find your females are more likely to go at the same time, or are they still scattered throughout the year? We have a few clutches in the incubator right now, but for the most part go in a full loop as far as when our girls are ready. One or two go at the same time, or close to, boxes go in the incubator, and about halfway through incubation, to just at the end towards pipping, new eggs are laid and are put in, and so on throughout the year. We don't do any changes other than what naturally happens with Washington weather effecting ambient house temperatures.
