We tried on day 4, to see if we could see anything. Nothing. So hard with brown eggs too. We tried again on day 11. We took pics of these. Hard to take pics when I've never taken pics of eggs before. I'll practice for next time I guess. These are the best ones that came out, although we candled all 10 eggs (one at a time with the rest in the incubator inbetween. Didn't want to hurt them, leaving them all out.) Don't know if any of these mean chicks or boiled eggs or just bad pics. Any ideas?
