Can a hard cooked egg show it's been fertilized?

[Kimi BK]

We just separated our roosters from our brood coop, and are done with chicks for this year (our first year of just letting our flock replenish itself... A little too successful!)

We don't want to share fertile eggs (we have a separate production coop). So we will be eating the brood coop eggs until they are "clear."

We eat way more hard cooked eggs than other, so we won't see whether those are fertilized while they are raw.

Is the "fertilized" bullseye obvious on a cooked yolk?

I've never had trouble seeing that a boiled egg is fertilized, especially since the bullseye is a slightly different texture from the yolk. But of course that assumes you didn't mash up the boiled egg, and just ate it in a tidy half.

I have never seen indication of fertile eggs once hard boiled.

Why don't you want to sell/share/etc. fertile eggs?

We are just not in a good time/place for this. We are overwhelmed trying to get our house built and can barely keep up with things, and we are badly managing our eggs. It's too hot here, and I have cracked eggs to plop out a developing embryo and I am not going to take the chance of accidentally sharing one of those! Even when we get our act together we are required to mark eggs as "fertilized" if we sell, and we just don't want to deal with it. I have no problem with anyone sharing/selling fertile eggs; we just aren't managing well enough at this point to feel like doing that.

That's an odd requirement. You have to crack the egg to find out.

If you do decide you're ready to sell or share eggs, fertilized or not, just remember to collect eggs every day, keep them refrigerated, and rotate the cartons. First into the fridge, first out. As long as they are refrigerated immediately upon collecting them, and kept cold, they won't develop embryos.

They don't need to be refrigerated.
It takes temps of ~100°F for a fertile egg to develop.
