Eggs that have mucus on them is this a fertilzed egg?

It's impossible to tell if an egg is fertilized just by looking at mucus on it.

Here's why:

* Mucus is normal: A thin layer of mucus is naturally present on the surface of eggs, even unfertilized ones. It acts as a protective barrier.

* Fertilization is internal: Fertilization happens inside the hen, before the egg is laid.

* Visible signs of fertilization: The only sure way to know if an egg is fertilized is to candle it (shine a light through it) and look for a dark spot (the embryo) or wait for the egg to hatch.

If you're concerned about the mucus:

* Freshness: If the mucus is excessive or has a bad smell, it could indicate spoilage.

* Storage: Improper storage conditions can also lead to changes in egg appearance and potentially increase the risk of bacterial growth.

Remember: It's always best to err on the side of caution and discard any eggs that appear abnormal or have a strong, unpleasant odor.
