Yesterday right after I put them on lock down my chicks started hatchin. I thought I still had 2 or 3 days left til hatch day. Now I have 5 chicks that hatched. I still have like 30 eggs left. Should I keep the eggs in the bator another 3 days? Do coturnix usually hatch all at once? I thought I read something about giving them more time to hatch than a chicken. That true?
