Because I wasn't entirely sure about the viability of my four hens eggs, I decided, after what is somewhere around the vicinity of 2 weeks, to candle the eggs. There is one egg in particular, that when I candle it, it looks fairly dense, a rather large majority of the egg is dark and the light will not penetrate it. One end of the egg has that wonderfully glowy area where there is what, yolk, or air, or something weird? And on the lower side of the egg when holding it above the light, I can see veins... BUT... as I slowly rotate the egg... and remember, I've never candled an egg before, so I don't know what I should be seeing... but its looks, to my inexperienced eyes, like there is fluid inside the egg, and as I slowly rotate it, the large dark mass always stays on top of the fluid as well. Maybe I'm not describing it properly, but have you ever seen those little things people have on their work desktops? It's a small globe with coloured liquid inside, and on top of the liquid there will be a dolphin, or a boat, and no matter what you do, you can't make the boat sink? The boat, whether the globe is upside down or shaken all around, is always on the surface of the coloured liquid? Thats vaguely what my egg reminds me of... Is anything I'm saying making sense? This is my first time with eggs as I said, so apologies if it sounds stupid... The other eggs I candled, two of them had very clear porous dots inside, so I disposed of them. And the fourth egg I'm just not sure of at all. I would love for some help!!!!
