I also candled tonight (day 7) and it looks like only 5 out of the 10 have developing embryos. Two out of the other half have what I think is some veining and a "floating speck" so I am think these two might be quitters and one has some shadowy +/- veiny areas so I wasn't sure. The last two eggs have been puzzling me from the start, as the eggs are a different shape and color than all the other eggs. The lady I bought them from had ducks running around the property and the thought briefly crossed my mind wondering what the odds were of these two being ducks eggs. I think it is a bit of a reach, but I guess if they were ducks eggs they would be on a whole different schedule of development than the chick embryos. It is more likely that these two just failed to develop, but just a random thought on my part I guess. I'm sure this has happened to someone at one time or another.
I put all of the eggs back and was planning to candle again on day 14. My broody was so cute tucking them all back under her and setting right back down to work.
Should I candle again sooner so I don't get exploding rotten eggs or am I ok to wait until day 14 to check again?
Thanks!

I had lots of concerns about exploding eggs, but none of my eggs exploded. I didn't trust my candling skills, so I didn't remove any of them. I left them for a total of 28 days, per broody experts advice, before I removed them. I opened them inside a closed ziplock bag, expecting the worst. They were totally undeveloped, but did not stink at all. They did not pop or explode when first cracked.
I am told that an egg will stink before it explodes, so there would probably be some warning. I've also been told that hens will sometimes remove an infected egg from the nest, but don't know how reliable that is. Ideally only clean but unwashed eggs with excellent shells should be selected for incubation, so that minimizes the potential for the eggs to become infected. Also, eggs should not be handled any more than absolutely necessary, and your hands should be washed and thoroughly dried before an egg is touched.
So bottom line, if you're not 100% sure that the egg is bad and has no potential to develop, don't remove it. You can always candle it later. If the egg is good quality and good egg hygiene has been followed, the risk of explosion is extremely low.
