Day 7...no veins, no embryo...what's wrong?

[Buckaroo]

Might be the dreaded x-ray with shipping, Kills the egg. Really hard to say, so many things can go wrong.

Last week I got a dozen eggs well wrapped. 3 were broken. 6 had : 1 blood ring, 2 no growth, and 3 had scrambled yolks. I am down to 3 at 10 days.

Exactly...a lot of possibilities, I know. I'm just trying to learn a little more about fertility, and what should be present in a 7 day old fertile egg.

Ok, here's some pics. The first pic is of one of the eggs candled the 6th night. The second pic is of one of the opened egg at day 7. I know these pics aren't the greatest, and probably won't help much, but maybe they'll give even a little insight into this mystery. I've also been told that the bullseye could be on the underside of the yolk. If that's the case with these eggs, and these eggs are fertile, shouldn't there be embryo development by day 7?

Also, if prior eggs from these same chickens (the week before) were fertile, then does that rule out infertility for these eggs? I'm sorry for all the questions, but this fertility stuff is really interesting. And another question...how often should fertility be checked?

This is an infertile egg courtesy of speckledhen.

Did you see this? This would be easier to see than and fertile ring because the fertility ring gets a washed out look.

Thanks for that pic, msbear. I didn't even find that in the eggs. As I said above, I was told it could have been on the underside of the yolk. So if it were on the underside of the yolk where I didn't look, then either the eggs were infertile or something else (like x-rayed)?

 

[Msbear]

the x-ray machine does not make a fertile or infertile spot dissappear. One of them is there, the pic just isn't focused enough to see it or it's on the other side.

 

[shelleyb1969]

If that's the case, now another question

...
Will x-ray cause the fertility ring to fade/disappear, or will it still be present, just no development?

 

[speckledhen]

No, you'd see the bullseye, even if xrayed.

And on that note... someone, somewhere was saying that despite popular belief, boxes aren't xrayed..... I can't remember the specifics, but if I remember the coversation correctly, the whole "X-Ray" thing is mostly just hype... I know the conversation included a postal worker, but I can't remember where I read it....
