OFF? Your incubator has that option? lol... With all your birds, I assumed you'd be running it 24/7, 365 days a year.
I just turned my cabinet incubator on for the first time in 3 months today. A lady who lives about 10 minutes from me posted a craigslist ad for someone to hatch eggs for her. She lives in a mobile home and the temps fluctuate so much, she has not been able to hatch a single egg from her birds. They all develop almost fully and then poop out when a swing in our weather comes.
Turns out, she is a BYCer as well. So, I met her and her son, set her eggs, and got my incubator turned back on for a set of SQ Australorp eggs I'm hoping to get from a swap this week.
