Can I store hatching eggs in the refrigerator?

No — a normal refrigerator (below 40°F) is too cold and reduces hatchability. Aim for about 55–65°F, near 60°F.

How long can hatching eggs be stored before incubating?

Set them within **7–10 days** for a strong hatch. Hatchability drops after that and is near 0% by 3 weeks of storage.

Do I need to turn eggs while storing them?

If you hold them more than 3–4 days, yes — turn them daily by tilting the carton or case so the yolk doesn't stick to the shell membrane.

Should hatching eggs be stored pointy-end up or down?

**Small (pointy) end down**, at about a 30–45° angle. This keeps the yolk centered away from the shell.

How to Store Hatching Eggs Before Incubating

Verified September 2026

The short version

Store hatching eggs at about 55–65°F (near 60°F is ideal) and ~75% humidity, small end down at a slight angle, and turn them daily if you hold them more than 3–4 days. Set them within 7–10 days for the best hatch — hatchability falls off after that and is near zero by 3 weeks. Let cold eggs warm slowly to room temperature before they go in the incubator.

The ideal storage conditions

Collected hatching eggs are alive but dormant — the goal of storage is to hold the embryo in suspended animation without killing it. Mississippi State University Extension puts the best storage conditions at near 60°F and about 75% relative humidity. A cool room, a basement, or a dedicated wine/egg fridge set warm all work; a normal kitchen refrigerator (below 40°F) is too cold and reduces hatchability.

Humidity matters because a dry room lets the egg lose moisture through the shell, enlarging the air cell before incubation even starts. Around 75% keeps that loss slow.

How long can you store hatching eggs?

Set them as soon as practical. Hatchability stays high for eggs stored fewer than 7–10 days under good conditions, drops progressively after that, and is near 0% after 3 weeks of storage. If you're collecting from a small flock to fill an incubator, it's fine to gather over about a week — just start counting from the oldest egg.

Position and turning

Store eggs small end down at roughly a 30–45° angle — this keeps the yolk centered and away from the shell membranes, where it can stick. An egg carton on a slight tilt does the job.

If eggs aren't going into the incubator within 3–4 days, turn them daily. You don't have to handle each egg: tilt the whole carton or case by propping up alternate ends each day. Turning keeps the yolk from settling against the membrane and the embryo from adhering.

Warm eggs before setting

Move stored eggs to room temperature and let them warm slowly before setting. Warming cold eggs too fast makes moisture condense on the shell ("sweating"), and that surface moisture can carry bacteria through the pores into the egg. A few hours on the counter is enough.

Once they're at room temperature, set them and begin incubation — see the day-by-day chicken schedule for temperature, humidity, and lockdown timing.
