Is this egg fertile?

Is this egg fertile? it is a very bad picture but if you look closley you might be able to tell, the reason im asking is because ive got to broody and am debating on using my own eggs or mixing them with baught ones

Yes it is fertile

The yolk in back with the white dot on it is fertile. I believe it's called a blastocyst. Unless you're wanting a particular breed, I recommend using your own eggs.

All chicken eggs have a blastocyst but not all are fertile. I can't tell from that photo if it looks fertilized or not. Sometimes leaving them at room temp for a day can help as the bulls eye becomes more apparent and there may be changes in color in the underlying yolk like it is swirled with a darker yellow.

Here is a nifty photo from another thread. Look at post #10

Thanks, Im not sure if they are fertile or not i might buy some and use my own and see if they hatch

The one in the back does not appear fertile to me. There is no ring around the blastodisc. Can't see the one in the front well due to glare, but it may have the bullseye and be fertile.
