Hey all! This is my first time incubating our eggs, and I have no idea what to look for when I'm candling. These eggs are 7 days old, and I have 8, with only about 3 that I think are growing. I took pics of the three that I think might be growing, and then one that I'm not sure of. 5 of the eggs look like this: Is there anything happenning here, or should I throw it out? (Sorry if the pic is horrible quality. It's really just an egg with a dark blob toward the fat end.) And then 3 have little strings that I think might be the beginning of veins: (I traced a little over the 'vein,' it was hard to see in the pic.) What should I see at day 7? And thanks!
