2 egg yolk questions

What is this, and is it safe to eat?

#2
Duck
Would this be considered the bullseye?? Like, is this one fertile?

Sorry I can't help, but I certainly wouldn't eat either. I'm picky that way.

First one is a bit of a glitch occurring at ovulation. Not unsafe to eat but may be unsettling to many, so nothing wrong with tossing it out or feeding it back to your flock (i would feed to the critters myself.... we have so many other eggs I can use I don't mind giving them the occasional treat when I find something a bit questionable)
Second one is not a bullseye, that is simply a normal unfertilized germinal disc

Well, unless you never eat eggs, I hate to tell you but you have eaten the second one every time.. that is a perfectly normal egg yolk exactly like you find in every egg ever laid

Don't eat anything you are suspicious about.

IMO - the egg is not a bullseye, so not fertilized.

If it was fertilized, it is perfectly fine to eat. Bird fertilized eggs are different than mammal fertilized egg. A mammal egg immediately begins to grow, even before being implanted on the uterus. A bird egg is inert. It does not begin to divide and produce new cells. It just sits there.

In order to start an embryo, the egg must be warmed to close to 100 degrees, and kept that warm for 24 hours. Then the inert fertilized egg begins to grow and the cells begin to divide. This allows a bird to lay and egg and leave it, lay another egg and leave it and so on, until the clutch looks right to her, then she settles in and broods, and all of eggs begin to develop at the same time. This prevents a staggered hatch. So within 24 hours, all the eggs hatch, the chicks are the same age, and she can get on with taking care of them.

Thanks!! Makes a whole lot of sense!
My girls don’t have a drake anymore, so makes a lot of sense being infertile! I had just been wondering if they were still hanging onto the sperm, and I could put some in my incubator. But I know it’s been WAY too long for that.

Thank you Mrs. K!
I suppose I need to learn more about the bullseye! lol
Yes! I always start my eggs in the incubator at the same time, bc of a staggered hatch
