Beside above, Can a hen lay a rotten egg?

Why do farm fresh eggs smell?

The smell is caused by the accumulation of trimethylamine (TMA) in the yolk. Most hens metabolize the TMA into another (odorless) compound, but brown egg layers don’t do that as efficiently, so when feeding canola meal, in some cases you may end up with–ick–fishy smelling eggs.

Why are Canadian egg yolks red?
