Think i posted a couple of picts twice.
It's hard to tell. Your pic's are a little blurry.
I agree the photos are very blurry, and long shots of a lot of birds...but I am seeing pullets.
The only one that worries me at all is this one because of the red coming in on the wings...but I think I saw the same bird in another photo and it had more red dispersed as a body color...but this would be the only one I would watch out for:
