I might just try it... I need to delay my hatch. After losing 2 chicks from prolapses, I really don't want to go through that again. So heart breakingYeah, my Brinsea has the auto cooling feature, but I haven't tried it. They have a lot of research to back it up. I haven't used it because it can delay your hatch, and I'm too impatient. Plus, I'm already getting great hatch rates in that incubator, so I figured why fix what's not broken?
