This will be my first year breeding darwins and wondered what I should be doing in regards to cooling them and there basking temps over the winter period. I am thinking that my temps should go down to about 17 with a 4 hour basking period in the mornings? They are currently at 28-30 daytime temps and overnight lows of 20 Basking lights and heating most of the day. I really dont know, and i have been very lucky with my childrens, I think they were made for each other as they breed pretty easily. Any help is greatly appreciated.
