Hi all, I set 6 Black Marans, 6 White Marsns and 25 Production Reds in my Humidaire model 20. I started with 40. I discarded one when I candled them that was really porous and oddly shaped. I put 4 under a broody hen and the rest are in the bater. I can't wait till the first candeling but I'm going to make myself wait till day 8.
