Hey everyone.
Does marans need more humidity than others to hatch?
It depends on your ambient humidity. I live in the very dry desert so I set my humidity at 65% for the entire hatch. I get 100% hatch rates using my bird's eggs. I use a GQF Sportsman incubator. You have to take into account your location, as humidity varies, type of incubator, still air or fan, etc.
