If you are breeding quail and incubating their eggs it is important to keep a record of hatchability and to calculate the percentage hatchability because this will help in evaluating incubation and hatch efficiency.
The percentage of hatchability is the percentage of eggs which actually hatch out as live young.
% hatchability = number of eggs hatched out/number of fertile eggs.
Quail Hatchability November 2007
25 quail eggs hatched out divided by 27 fertile quail eggs = 93% hatchability.
This is a great hatchability rate for the first time we have incubated quail eggs.
