are they fertilized eggs?

my two cockatoos laid eggs about a month and a half ago. One of them laid 10 the other one 4 and i also have a male. For the first month the one that had 10 eggs sat on them then stop so i pretty much gave them to the other one and they are always warm..

But today i saw a broken egg like it had some yellow stuf in their in it was dry... Also another eggs was gray so i separated it from the other ones.. but how can i know if they have something inside. I put them in the light and i can see something yellow but its only like either on the pointy part of the egg or at the larger part at the bottom and it looks like its not a liquid substance. So do you think they are still alive..??


Thank You
