Hi, first time to this forum. I'm incubating 10 WH in a few days and found this posting on humidity. https://poultrykeeper.com/incubatin...hat-humidity-should-i-use-to-hatch-duck-eggs/ It's a compelling write up and I love good data. However, 40% is lower than anything else I read online. Like anyone, I'd love to do my best by these eggs. Has anyone hatched the Welsh and can offer tips? As far as weight, I know 13-14% loss is optimal, is that an average per day for 28 days?
