So I tried candling for the first time about 20 mins ago, I have absolutely no idea what I am doing and all the eggs looked exactly the same. I have read the topics on candling so I know how to do it I guess, but I have no idea what I am even looking for. Seen the pictures from day 7 from the topic on top, but mine look nothing like them. They were all dark at one end, and almost all through the egg was dark. Then at the other end I could see through it. I have no idea what this means. Anyone know? Are they all bad?
