Shipped Egg Question some one please see if you know the answer

Whatever the reason, the egg she cracked open was not developing. By day 6 there should be a developing embryo....not a bullseye.

The other side of this entire discussion is over in the two crazies setting buckeyes thread. I don't know if its the other side of this particular purchase or not, but the same question. She says if the egg was ever fertile, you can find the bullseye even after having incubated it for a number of days. In otherwords, fertile, but didn't develop. vrs never fertile. My problem when I try this is half the eggs by this time have a weakened yolk and it breaks and I cant see anything.

yep that want i want to know if and egg is fertile can you see the bulls eye even after it has been put in the bator. I know it was not develop because see did not see anything. But it was a shipped egg and we all know that some of them do not develop.

You will find your answer here, along with photos of each possibility. Excellent article ....

The problem Kathy is I still don't see a picture of the bullseye in a fertile incubated egg that didn't develop. I'm not saying I don't believe you, I'm just saying there isn't a picture of that here.

The one that says this .... shows the picture...

Blastoderm without embryo (BWE) and infertile - chicken.
A comparison between two candle-outs. The infertile egg (right) shows no development, the 2-1/2 day BWE (left) shows the typical extra-embryonic membranes surrounded by a blood ring.


Fertile, pre-oviposital death, turkey. This is a type of FND.(fertile, non develper)
A rarely diagnosed condition. The egg was incubated for 3 days before being broken out. The blastodisc has deteriorated but still has the characteristic shape and size of a typical fertile blastodisc.


Positive development (PD): turkey.
A fertile egg that began to develop and then stopped. Candled, it appears to be clear. Note the absence of blood, as compared to the BWE illustrated above.

*Also, look at the very last 2 pictures ... the blastoderm (bullseye) got larger ... it was a fertile egg.

Why the heck would you crack open an egg that was incubating for six days anyway?

People can be very strange sometimes.

Unless an egg is perfectly clear, and maybe not even then, I would give up on it at six days. Even some of the more experienced people say wait until 10 days if you really want to see something when you candle.

Catherine,
As the study says:
In cases of poor hatches it is important to identify the cause of the trouble as quickly as possible. Poor yield may be caused by a failure in fertilization or by excessive mortality of the embryos do to a variety of factors. A list of problems, causes and possible solutions may be useful in trouble shooting incubation problems (Poultry Fact Sheet No. 33 Incubation Problems -- Some Causes and Remedies).

Candling of hatching eggs during incubation and examination of the clear eggs or dead embryos is a useful tool for hatchery managers. Undoubtedly managers will want to monitor many other parameters in the hatchery to assure optimum hatching success. These might be parameters such as temperature of egg storage room, shell quality, incubator temperature, incubator humidity, chick quality, hatching percentage, bacterial counts in air or on hatchery surfaces, and egg moisture loss during incubation. This publication illustrates the appearance of eggs during candling and how to identify infertile eggs and early dead embryos during break out.

Is that what you are talking about .... the reference page?

 

[IggiMom]

That was a very interesting reference page, and I will look it over some more.

Still, if I had shipped eggs I don't think I would break one open at six days in, unless I was just really, absolutely sure of what I was doing. I would want to give it a little more time. I was talking about the person who the OP said was unhappy with her shipped eggs.

Thanks for the reference. Every time I see one of these I study it to see if I can learn something more.

I have some eggs that I think perhaps died in the power outage.

They are sort of clear with little dark blobs in them. I just HATE eggs like this, because although I THINK they are gone maybe they aren't. It just isn't as clear as an egg that is just, well, clear.

In fact I did see one like this, and then, lo and behold, I could see something moving in it.

If you know of any other references that have more pics of eggs that are further along in incubation but are gone, please let me know.
