Different stages of development?

Out of the 9 Buff Orp chicks, which are a week old as of yesterday. I have two that do NOT have the beginnings of tail feathers or as well developed wing feathers.
The other chicks are beginning to get body feathers as well.

Does this mean anything sex wise?

 

I asked a friend that has raised chickens what he thought and he said they looked to be all pullets. *And that I have some special power over my husband since I convinced the hubby to be ok with chicks in the living room
Honestly. If I had special power over my husband I wouldnt use it on chicks in the living room. We wouldnt live where we do! *

I dont know though. Our camera is missing. I had it Monday on our trip, but havent seen it since. So I cant take any pictures to post here and see what you all think.
I would wait and see, but 6 of them technically arent mine I am just holding them for someone til the NH Chicken Stock which is next Sunday. Even having 6 of them leave is going to be hard. They are all just so sweet and developing their own little personalities. The only one I know that is staying is my Black Cochin, Vivian. Who I hope doesnt turn out to be a Victor
