After I finished candling, I got to thinking, how do the bad eggs really look like if I cracked them open , what is it inside the egg that makes it look that way above the candling light??? So I grabbed an egg, that when I candled it, it looked clear, with a weird dark yolky rig around it, and craked it in a bowl and it pured out like water, yellow water that is, and it smelled like egg, so it was an infertile that cooked I guess, it was just yellow liquid . Then I grabbed one I wasn't sure about (two I wasn't sure about,looked the same), when I candled it it was all dark with the exeption of the air sack. The ones that I knew were good looked like the typical candled eggs, little embryo with vains, but these two didn't look like any of them, So I decided to crack one open , big mistake . There had been a nicely developed embryo, and I killed it . I was heartbroken , I threw it away sad . But why did these two eggs look all dark when I candled them, and not like the rest. It wasn't like the embroys were ahead in development or anything, the one I opened looked just the same size as the good ones, but yet, when candled, looked completly dark with the exeption of the air sack why??
