A goose does not have a gestation period. Birds do not carry developing young inside the body: the female lays an egg and the embryo develops inside that egg, outside her, warmed either by a sitting parent or by an incubator. The correct term is incubation, and it is measured from the day the eggs are set or the parent begins sitting, not from mating and not from the day the first egg appears.
Key goose incubation facts
- Goose eggs hatch after about 30 days of incubation, with a normal range of 28 to 32 days.
- A typical clutch is 5-8 eggs.
- Incubation only starts when the eggs are sat on or set, which is often days after the first egg is laid.
- Poultry eggs are usually set in an incubator at 37.5°C and 55% humidity, with turning stopped a few days before hatch.
How to count the days
Day one is the day the eggs go into the incubator or the day a parent starts sitting continuously, not the day the first egg was laid. Eggs can be held for up to a week before setting without much loss of hatch rate, and holding them keeps the clutch hatching together. Stop turning around day 27 and raise humidity for the final days. If nothing has happened by day 34, candle the eggs before discarding them: a cool incubator can delay a hatch well past the average.
How long do goose eggs take to hatch by breed?
Most domestic geese hatch in about 28 to 32 days, with lighter breeds at the shorter end. Large breeds such as Toulouse and Embden often take 30 to 32 days, and Canada geese take about 28 days. Egyptian geese, which are really shelducks, also hatch in about 28 to 30 days.
What temperature and humidity do goose eggs need?
Most hatchers run goose eggs slightly cooler than chicken eggs, around 37.2–37.5°C in a forced-air incubator, with humidity about 50–55%, rising to 75% or more for the hatch. Goose eggs benefit from daily cooling and misting from about the second week, as a goose leaves the nest to feed and bathe.
How should goose eggs be turned?
Goose eggs are often too large for automatic turners. Lay them on their sides and turn them by hand at least three to five times a day, rolling them a half turn each time. Stop turning about three days before the expected hatch.
What is normal during a goose hatch?
- Goslings can take a day or more to hatch after the first pip.
- Keep humidity high and the lid shut; opening it dries the membranes quickly.
- Goslings grow fast and need grass or chopped greens from the first few days, alongside starter feed.
