If you are 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.
Calculating Hatch Rate
The percentage hatch rate is the percentage of total eggs hatched out.
% hatch rate = number of eggs hatched out/number of eggs set in the incubator.
