This is only my second time to hatch guineas. Can they stay in the hatching tray 3 days like a chick? I don't like to open the door during a hatch but I also don't want to starve anything.
I took them out when they were completely dry. I did not see any point in making them go without food/water for three days just because they can. Of course, I waited until all had hatched before I did this.
