Dirty Eggs, How to Prevent Them and Whether to Wash
Dirty eggs are a housekeeping problem, not a hen problem. Most muddy or manure-smeared eggs come from birds sleeping in nest boxes, too few boxes, damp bedding, or infrequent collection. Fix the nest setup and the eggs stay clean. If you must wash, use water warmer than the egg, wash right before use, and refrigerate washed eggs, because washing removes the protective bloom.
Most likely causes
- Roosting in nests
Hens that sleep in boxes fill them with manure overnight.
- Too few boxes
One box per four hens keeps traffic and breakage down.
- Wet bedding or muddy runs
Dirty feet track straight into the nest.
- Infrequent collection
Eggs left all day get stepped on and smeared.
What to do this week
- Block nest boxes at night for a week to break the roosting habit.
- Add roost bars higher than the nest boxes so birds prefer them.
- Keep deep, dry nest bedding and refresh it weekly.
- Collect eggs twice a day, and add drainage or mulch to muddy run areas.
When it is worth a closer look
- Eggs are wet with runny droppings, which can indicate a health problem in the flock.
- Nests are persistently damp, raising mold and respiratory risk.

Common questions
Should I wash fresh eggs?
Only right before use. Unwashed eggs keep their bloom and store longer at room temperature in many regions.
Can I sell dirty eggs?
Rules vary by state. Many require clean, unbroken eggs, and some restrict washing methods. Check your state's rules.
Keeping eggs clean and safe in a backyard coop
Dirty eggs are mostly a coop setup problem, not a hen problem. Mud from the run, droppings in the nest, and broken eggs smearing the others are the usual causes. Fixing those is easier than washing every egg. But if the dirt is mostly runny droppings, it is worth checking the hens too.
Fixing the nest boxes and coop
- Keep nest boxes lower than the roost bars, so hens sleep on the roost and not in the nests.
- Block nest boxes at night if hens keep sleeping in them.
- Add fresh, dry bedding often. Straw, shavings or pads all work if they are kept clean.
- Collect eggs at least once a day, twice in muddy or hot weather.
- Add gravel, sand or a mat at the coop door so muddy feet get wiped before the nest.
- Remove any broken egg right away and replace the bedding under it.
The roosts and nest boxes guide covers spacing and heights.
When dirty eggs point to a health problem
If eggs are coated in watery or stained droppings, look at the hens. Runny droppings stuck to the vent feathers can mean diarrhea or an infection. Read watery droppings if you see loose stool, and vent gleet if a hen has a crusty, smelly vent. Heat can also cause watery droppings because hens drink more.
To wash or not to wash
Eggs come out with a natural coating called the bloom that helps keep bacteria out. Many keepers leave clean eggs unwashed and store them that way. For lightly soiled eggs, dry brush or gently wipe the spot. If you need to wash, use running water that is warmer than the egg, never cold, and never soak them, since that can pull bacteria through the shell. Dry them and refrigerate them after washing. Once washed, keep them in the fridge.
Which eggs to throw out
- Cracked eggs, especially if they sat in dirty bedding.
- Eggs that are heavily coated in droppings.
- Eggs of unknown age found in a hidden nest. Float test them and toss any that float.
Protecting yourself and your family
Healthy chickens can carry salmonella on their feathers, feet and eggshells. Wash your hands with soap after collecting eggs or handling birds. Keep egg collection baskets and coop boots out of the kitchen. Cook eggs fully for young children, older adults and anyone with a weak immune system.
Common questions about dirty eggs
Should I wash fresh eggs before storing them?
Many keepers do not, if eggs are clean. If you do wash them, use warm water and refrigerate them afterwards.
Can I eat eggs with poop on them?
Lightly soiled eggs with intact shells can be cleaned and eaten. Heavily soiled or cracked eggs should be thrown out.
Why are my eggs suddenly dirty?
Check for hens sleeping in nests, wet bedding, a muddy run, or a hen with runny droppings.
