Oh my gosh..nevermind, I'm clearly an airhead!! I asked my husband about it a short bit ago when he was home for lunch. He went in the bathroom (no windows in there) with the egg and closed both doors. He came back out laughing his butt off at me and I was like what!? He said "There's only one embyro in there honey, it moves when you move it, so if you're moving the egg to look around in there, it moves with you - probably made you think there was another one."
Conclusion: Only 1 chick in there and it's probably not going to be in there much longer (I didn't know they moved around when you moved the egg) - I probably scrambled the poor thing to death moving the egg around to look inside.
I'm new, cut me some slack please. I'm learning as I go.
