Are my eggs fertile?

[Hestia]

I very inexperienced at incubating, I had a successful first hatch from bought eggs (20/25) for my first time, and thought for my second lot I'd add some of my own eggs. I checked them for fertility and to my (inexperienced) eye I thought they were fertile. But at candling them not one had developed. Not even a start then a stop. Was I not seeing a fertile spot when I checked my eggs? I'll attach a photo of a fresh egg that I cracked today, I think it looks fertile but am I wrong? Why would none start to develop if they are fertile? Thanks for any help in advance
(the first photo has the flash on so it's reflected)

Hello Heista, this is actually pretty interesting cause I see a little white dot on the lower part of the yolk?
Not sure if it's anything that's growing though, may just be part of how this yolk is.
Were you thinking of just seeing if there was a little fertility after cracking the egg or seeing if you could actually grow a chick?
Just wondering cause this is cool to see since I've seen people try to save the fertility of a chick from the crack egg before.

Hi there
No I only cracked the eggs to check the spots to see if they were fertile. When it looked like the cracked eggs were regularly looking fertile I used whole un cracked eggs to incubate.
I also have a hen sitting on eggs and am wondering if she's wasting her time

Oh, okay. Best of luck with your mama hen!!

I'd go with fertilized. Mine that aren't have just a solid opaque spot. Yours I don't see the bulls eye around it, but they don't look infertile to me compared to mine.

Try incubating a half dozen or more for 3-5 days then crack them, fertile eggs will show blood or vein development and infertile will not. Looking at an unincubated egg can be suggestive but not conclusive. And get eggs from multiple hens/ roosters if you can as infertility can be an issue for particular birds.

OK thanks. I only have one rooster so a different rooster isn't really an option. We were given him and I'm starting to wonder if he's older than I thought he was which I guess affects fertility, would it affect a fertile egg developing as well though?

You don't have to crack them

You don't have to crack them

Just candle them

How many hens do you have?
