Candled our redfoot eggs

[Tweak]

43 days ago our female laid her first clutch that had more than just 1 egg. I have attached 6 pictures to see your thoughts on them as well as a picture of an egg she laid 117 days ago. The older egg and a few of the youngest eggs have thicker shells, I am assuming that is because those were her first few eggs. She had laid 1 egg last year that we incubated for over 200 days before it cracked and we tossed it, but it also had a harder shell.

I've hatched....and exploded an equal amount of REDFOOT eggs. I candled them and checked for chalking and to me, they looked about the same unit some hatched and some cracked or popped in a smelly mess.
It's an art I haven't mastered.
I'm sure someone with better luck and better eyesight will be along soon

Eggs number #2, #3 and #4 look a bit rough/calcified but I am not sure @Tom

Update, we are at day 70 and while several of the eggs look different, #6 is the only one that whatever is inside hasn't settled on the bottom.
