We've just discovered, that our hens have either mites or lice. My question is: Can we sell the eggs as normal OR Should we wait until we've gotten control of the pests?
eggs are fine for now. If you treat with dust, the eggs will continue to be fine. If you treat with insecticides that penetrate the skin, or are ingested, there will be a withdrawal time. Try searching under "mites and lice" on this site, you will find tons of into.
