Fertile yoke check

[threeepeat]

I'm new to checking coturnix eggs for the fertility "bullseye," as people are calling it.

This morning I cracked open yesterday's 4 eggs from my four layers.

#1 Double yoke, one yoke was cut by my scissors. I do not see a dot in the remaining yoke so I'm assuming this was an immature egg (based on a video I saw)

#2 No dot, but had a black fleck of some kind

#3 Has a dot and seems to have a bullseye ring

#4 Has a dot but I'm not sure if it has a full bullseye ring. It also has blood streaks. This egg is from my big Range hen that all the roos seem to prefer (not Scarlet as I had previously thought)

Any thoughts on which egg/s are fertile, and what causes the black fleck and blood streaks? Are these still edible?

Thanks

They're still edible, non look fertile to me.

The lower one in the second and third pics looks fertile to me.

I see a very faint ring around the blastoderm but it really doesn't look like what a fertile 'bullseye' should look like!

Good to know. I usually check fertility by incubating and candling around day 5.

Thanks guys. If it's not that clear cut for you pros, then how am I gonna figure this out? Haha joking, but yeah the reason I'm checking the yokes now is because I don't want to start to incubate eggs from these young hens until I know the rooster is making hay.

Well, sometimes it is hard to tell....the one with the blood is definitely not fertile. As @Nabiki , says, incubate for 5 to 7 days, candle and then you will know!
