My first batch of eggs is at like Day 8 1/2, LOL I just couldn't wait til day 10, so I just candled one to see. I used a flashlight, should I put a piece of fabric or something over it with a hole? I first did a fridge egg, so I could see the difference. My incubator egg has a dark blob, it looks like its on one side though, not the middle. Is that a viable egg? I am assuming that means its fertile, right? Yay, my Roo is fertile! This is our "practice" batch before I buy "real" eggs! I have already decided it is way too small, I could only fit 31 eggs in there!
