how long do geese sit on eggs

Geese usually sit on their eggs for about 28–30 days, and sometimes up to around 35 days for larger breeds, starting from when they begin full-time incubation rather than when the first egg is laid.

Quick Scoop: How long do geese sit on eggs?

Once a goose decides she’s truly broody and settles in to incubate, you can expect:

• Typical incubation time: about 28–30 days until hatching.

• Larger or heavier breeds: can stretch closer to 32–35 days in some cases.

• She usually lays a full clutch first (often 8–12 eggs), then starts serious sitting so most eggs hatch together.

A useful way to think of it: from the day she stops focusing on laying and really settles on the nest, you’re looking at roughly one month until goslings.

How constantly do they sit?

Broody geese are very dedicated, but they don’t glue themselves to the nest 24/7.

• Many geese take short breaks, often 10–15 minutes, a couple of times per day to eat, drink, and bathe.

• Some will occasionally stay off for up to about an hour, especially more relaxed or younger birds, but then hurry back.

• Very intense first-time mothers may barely leave the nest at all, which can be risky for their own health if they don’t eat or drink.

So while it looks like she “never moves,” most geese do slip away briefly and the eggs stay warm because of their insulation and the nest lining.

What if the eggs don’t hatch?

In backyard flocks and in the wild, it doesn’t always go perfectly.

• Most geese will eventually give up on a non-hatching clutch sometime after the normal 28–35 day window, though the exact timing varies by individual.

• Owners sometimes report geese stubbornly sitting well past a month on infertile eggs, only leaving when they finally lose interest or are encouraged off the nest.

As a rule of thumb, if you’re past 35 days of solid incubation and see no signs of hatching, fertility or early embryo loss is a likely issue.

Little “story” snapshot

Picture a spring morning: your goose has spent a week laying an egg every day or two, barely paying them attention beyond covering them with down.

Then one day, she settles in, fluffs herself over the nest, and suddenly that’s her world. For nearly a month she hisses at anything that comes close, slips away only for quick meals and baths, and returns to gently turn the eggs before tucking them back under her breast. Around day 28, you hear faint peeps from inside the shells—and within a day or so, a line of damp, wobbly goslings is following her to the nearest water.

TL;DR

• Geese sit on eggs for about 28–30 days, sometimes up to ~35 days for larger breeds.

• They sit almost constantly but may take short breaks of 10–60 minutes a few times a day.

• If nothing hatches after roughly a month of true incubation, the clutch may be infertile, and most geese eventually abandon it.
