If we need to trace chicks from certain eggs they get hatched in separate drawers (if in the redwood) and or in baskets if in the dickey (which I try hard not never hatch in) then its easier to leave everyone alone until all are hatched and mark them at once.I've been wondering... How do you mark chicks so you know who came from which egg and subsequently who it's parents are? Do you have to take each chick out during the hatch?
