I candled 4 of my 12 eggs I've got set under a broody now, and 2 were clear, and 2 had stuff going on, sort of like half the egg was dark and I could see spiderwebby stuff in one. Just used a flashlight in my dark bathroom, so it wasn't super clear, but definitely 2 were more busy than the other 2. I marked the bad two, and put them all back. Gonna candle in another 6-8 days, the 2 bad ones and 2 other ones.. if the 2 bad are still bad, will remove then. Very excited! Going right now to get my new dozen hatching eggs. YAY!
