I took pictures tonight so that you can see their legs and backs better. I woke them up to take pictures and they weren't happy, they were so sleepy!
Which part is the wing bow? I was looking closer at the wings and it seems like #'s 1 and 2 both have wings with feathers that are more sparse, while #3 and #4 have fully feathered out wings already. Their necks are different too, some of them have a lot of missing feathers on their necks, they look so goofy when they're standing tall during the day looking around. I tried to figure out a difference in coloring on their combs, but I couldn't tell and I almost got pecked in the eye.
My toddler thought that was hilarious. I did notice that on some of them the teeth (?) on the comb are larger while on other chicks the comb has smaller teeth that are closer together and more evenly sized.
Is there some way to sex chicks based on feathers right next to their vent hole? Awhile ago I saw a video on YouTube of a huge chicken plant, and it showed workers flipping just hatched chicks upside down and checking their bums for something. I tried to take a good look at mine, but I couldn't figure anything out and now my toddler keeps trying to flip them over to look at where their poo comes from every time I turn around. LOL.
Here are some pictures...

(This one was cuddled up with its head tucked under its wing! The first chick to do that. I felt bad disturbing her.)
