A hatchery which is sited at high altitude (1500 meters (4921 feet) or more above sea level) faces some particular challenges; slower embryo growth, longer incubation periods and lower hatchability have to be expected.
This document is a practical, on-farm tool aimed at helping farmers identify hatching egg shell issues. For each egg shell abnormality there is a picture showing what the abnormality looks like
At around 18 days of incubation, eggs have to be taken out of the setters, moved from setter trays to hatcher baskets and transferred into hatchers for the last 3 days of incubation.
