If they're trying to internally pip and can't, they might end up DIS. You're there and can see it in person, so you know better than I do about what feels right. Have you hatched Runners before? Do you have an alternate calibrated thermometer and hydrometer inside the incubator? Have you already raised the humidity? I don't mean to second guess you by any means, so please know that I don't mean to disrespect you in any way

I LOVE Runners and hope you'll share pictures of them. I will have some one day. What colors are these eggs from? Please accept my apologies. I get excited talking about ducks

I'm outside locking up my little quackers right now, way past bedtime
