Beyond the nest box

Clean eggs begin with clean nests and frequent collection.

Collect at least daily, remove cracked eggs, keep nest material dry, and learn the egg-sale and refrigeration rules that apply where you live before selling or giving eggs away.

About the author

Sage Mercer

I keep a mixed laying flock in northern Nevada, with a large run and supervised free-range access. My guides combine what I have learned in the yard with veterinary, government, and university-extension references where measurements or health claims need support.
