How to Collect, Clean, and Store Farm Fresh Eggs
Farm fresh eggs are one of the best things about keeping a backyard flock. But handling them correctly — from nest to refrigerator — matters for both quality and food safety. Here's what you need to know.
When to Collect Eggs
Collect eggs at least once a day, ideally twice in warm weather. The reasons:
- Eggs left in the nest box get dirty, cracked, or eaten by hens
- In summer heat, eggs deteriorate faster and can develop bacteria more quickly
- Frequent collection discourages broodiness in hens that might otherwise sit on a clutch
Most hens lay in the morning. A midday and evening collection covers most situations.
To Wash or Not to Wash?
This is one of the most debated topics in backyard egg keeping — and the answer depends on how you plan to store them.
The Bloom (Cuticle)
When a hen lays an egg, it's coated in a natural protective layer called the bloom (or cuticle). The bloom seals the pores of the eggshell, preventing bacteria from entering and moisture from escaping. It's the egg's natural preservation system.
Unwashed Eggs
Eggs with the bloom intact can be stored at room temperature for 2–3 weeks — this is standard practice in most of Europe and many other countries. The bloom keeps them fresh without refrigeration.
If your eggs are clean when collected (clean nesting boxes = clean eggs), you can simply wipe off any debris with a dry cloth and store them on the counter.
Washed Eggs
Washing removes the bloom. Once washed, eggs must be refrigerated and should be used within 5–7 weeks. This is the standard in the US — commercial eggs are washed and refrigerated, which is why American grocery store eggs require refrigeration.
If you wash your eggs, use water that is warmer than the egg (not cold water — cold water causes the egg to contract and can pull bacteria through the shell). Use a mild unscented soap if needed and dry immediately.
Our recommendation: Keep nesting boxes clean so eggs come out clean. Dry-wipe any debris. Store unwashed eggs at room temperature for up to 2 weeks, or refrigerate for longer storage. Only wet-wash eggs that are visibly soiled, and refrigerate those immediately.
How Long Do Farm Fresh Eggs Last?
- Unwashed, room temperature: 2–3 weeks
- Unwashed, refrigerated: 3–5 months
- Washed, refrigerated: 5–7 weeks
Farm fresh eggs last significantly longer than grocery store eggs, which are often 4–6 weeks old by the time they reach the shelf.
The Float Test
Not sure if an egg is still good? Place it in a bowl of cold water:
- Sinks and lays flat — Very fresh. Eat it.
- Sinks but stands upright — Still good, use soon.
- Floats — Old or spoiled. Discard.
As eggs age, the air cell inside grows larger, making them more buoyant. A floating egg has too much air and should not be eaten.
Storing Eggs for Selling
If you're selling eggs, North Carolina regulations require that eggs sold directly to consumers be clean, properly refrigerated, and labeled with your name and address. Keep a clean carton supply on hand and date your cartons so customers know when eggs were collected. See our full guide: Raising Chickens for Profit →
Cracked Eggs
Cracked eggs should be used immediately or discarded — never stored. Bacteria can enter through cracks quickly. If you find a cracked egg in the nest, collect it separately, inspect it, and use it the same day if the membrane is intact.
