I can confirm 3 eggs are developing as I saw embryos dancing around in them last night, including the patchy egg that had part of the color washed off of it!!

I believe all three of those eggs belong to Nadine (I wasn't 100% sure on two of them when I set them, but comparing them to the egg I know for sure is Nadine's now makes me think they are). This has me a tiny bit concerned that only her eggs were fertilized, as she's had chicks with Murphy before while the other two haven't, and I'm not seeing any veining or anything in the others even though only one actually looks like a dud to me.

I'm doing the 'official' candling for the week tonight, day 6 for two of the eggs and day 8 for the rest, so I'll take a closer look then.
