Cute, cute, cute kids, human and chickens (and you too Elizabeth)! And I agree the light brahma is a pullet. They look rooish when they're young but she would have a much more pronounced comb by now.
Had a funny thing happen today. When I went to check on the broodies, one of them had moved an egg out from under her. I saw cracks all over it so I took it. I was surprised to find it was pretty heavy so I sat it down to carry down to the trash and to decide if I had the guts to eggtopsy it. I took it in the barn where it was dark to see if I could candle it (it's about day 7). I don't have much experience but it wasn't clear. I decided to give all the chickens some scratch and fresh water to see if I could get the broodies to get off the eggs so I could count eggs (about 30 between the two). It worked and they both ran out like crazy girls and got some fresh water and treats. Back to the egg....I decided to just peel back a little part of the egg at the crack and to my surprise it popped off...only there was shell still there! I peeled another piece and same thing! Turns out this egg got moved into the shell of a broken egg...same color, same size! I don't know if the chicken thought it was broken so she moved it out from under her or what but I picked off most of the stray shell and put it next to the girl that had the least amount of eggs. Checked back when I went to lock the coops and she took it back. It'll be interesting to see if it stays put or she moves it out again.
