I have 50 hens and 1 rooster. I'm seperating 10 girls with the rooster. I have a 30 egg incubator, I'm planning on attempting to hatch all 30. But at most I'll be getting 8-10 a day from the 10 birds, should I just leave them in the egg flats until I have 30 and put them in then load them up in the incubator when I have the 30?
