How to tell the difference between a fertile and infertile egg.

    You can tell if your egg is fertile because if you crack it open, a fertile egg will have a circle ring
    with a dot in the middle of it. Which is called a bullseye. A infertile egg won't.

    A infertile egg will have a circle in the middle, but not a ring around it.
    Hope this helps you all!

    Sorry Hybridchucks, didn't mean to be abrupt or unceremoniously curt! I tend to see things as black and white....not much room for gray. It's just that I raise/breed some very rare and expensive birds and would hate to kill a potential chick by that method of checking fertility. I don't raise chickens, geese, ducks, emu, or peafowl anymore, just pheasants, quail, and prairie chickens. I have several cabinet incubators, so I just incubate the eggs, after 8 to 10 days, I candle and toss the ones not developing.
    As I said, "this is a good reference for those that don't know what to look for" and choose to use this method". Thank you for posting this article.

    That's all fine and dandy! but you have to open the egg to be able to tell....wasting a pontenial chick.
    I guess it's fine if you have been incubating them and when candled showed no development, it wouldn't hurt to crack it open, but there again, if it isn't developing, it's probably not fertile anyway!
    Other than that, there are probably a lot of people that don't know what to look for, and therefore, this is a good reference. Just my 2 cents.

      but....if u want to know if the rooster is fertilising the hens eggs, that is how u find out, open 2 or 3 and if they are all fertile u can incubate the others.........don't be so abruot.
