How to Tell a Fertile vs INfertile Egg (Pictures)

[aart]

So what do you think about the egg on the right??

Am I correct in believing that the egg on the right looks to have been sat on for a day or two, and this is the developing embryo?

I'm guessing maybe it was frozen.

So... is the bottom one fertile? It looks like a perfect circle compared to the other two. And what's that big line in the one in the top left? These have been in my fridge and I just decided to start "looking."

Okay, the pic is upside down! So now I think the top is fertile and the bottom right has the line...

They all look fertile to me - usually unfertilised eggs have a small white dot the size of a pin head rather than a larger spot with a denser middle like the eggs in your picture

Ooh! So once a hen starts laying fertile eggs, how many days will she lay eggs that are fertile? It's not a one egg thing, right?

One mating can keep fertile eggs coming for a couple weeks, chances are the rooster will keep her 'tended'.

Wow. She is definitely well-tended. Any egg she even thinks about, then, should be fertile, lol.

At this time of year you can be pretty sure that probably all of her eggs will be fertile , happy hatching !!

Oh I'm so glad you posted this! I originally thought that if there is a little red dot that meant they were fertile. Because some eggs have a red dot on the yolk and some don't.

That is just a blood spot, or meat spot. It is from blood or tissue in the reproductive tract as the egg moves through. It's fine to eat them (fertile eggs are also good to eat.)
