My indian runner pair started laying a while back, and we checked fertility a few times. I'm comtemplating incubating a pile they have going. I had read somewhere the won't start laying (broody) till they have a big stock pile. These guys are about to be a year old. Should I leave the eggs out there to convince them to lay? Or should I take 'em in and incubate since the bator is finally empty? If I choose to incubate them what does the humididy need to be? I've read 55% and 85% so those are pretty far apart. Any help would be awesome. I'm new to ducks so excuse my common question please.
