Are these eggs fertile??

[BuffOrpington567]

Try cracking open one of your recently laid eggs and looking for a small white bullseye on the yolk. You may have to move it around a bit to find it but it will look like this. If you see it, than it is fertilized.View attachment 1757900

I did do that and saw it on the egg so it might be fertile but non of the eggs are showing veins or anything and on days 5. We got a new cock so I don’t know if he’s firing blanks or anything
