Incubation Records

Keeping personal records is important for identifying performance issues or problems in incubation.
Name of species, setting date, transfer date, first and last hatching date, number of eggs set, number of fertile eggs, number of chicks,
and % hatchability should be recorded for future reference. We also suggest candling you eggs to check for infertility.
Hatchability rates can vary by species. Hatchability can be calculated by dividing number of chicks by the number of fertile eggs.
