I did lower temps this year... at roughly 8pm I would cut the power to the flexwatt on my breeder female and breeder male racks, bringing them to the ambient room temperature of 80F at the lowest. During the day I offered a 88F hot spot from the usual 95F hot spot, with cool side temps still at 80F.

Out of doing this....I only got one clutch out of five pairings, and it was late anyways. Despite my regulation of the room temps, the animals must've been able to tell that it was still winter out in MN here.

I didn't get really good follicle development until mid april, when the outdoor temperatures here finally starting climbing, despite returning them to full heat cycles about mid March.

Am I going to cool next year? Probably not... they go when they want to go.
