When breeding quail and incubating their eggs it is important to keep a record of the percentage of total eggs hatched because this will help in evaluating incubation and hatch efficiency. I have recently hatched some quail chicks and wanted to share the hatch rate with you. You can calculate hatch rate in the following way;
% hatch rate = number of eggs hatched out/number of eggs set in the incubator.
This October I placed 31 eggs in the incubator and 20 hatched out. So 20 divided by 31 equals 0.6451612 times by 100 equals 64.5% hatch rate.
