Newbie wing question

[ekd]

I was watching my five week olds outside playing and noticed something. Three of the four were holding their wings low, with the tips under their tails, kind of over their vent. The fourth had hers held with her wingtips above her tail. Is this significant?
Pictures attached. The brown one is the one in question. I think she might be a Starlight Green Egger?

As far as I know, it is insignificant. I think it depends on the breed.

These two roosters are likely perfectly healthy, and just carry their wings differently.
