Pretty sure these are a mixed breed???

I got these from a local tractor supply - they were labeled as Australorps.
A few have copper/orange neck feathers, most are gray/blue, there is one that is mostly black with a little bit of gray. All have black beeks, some have yellow feet/legs, most seem to be a combination of yellowish grayish feet/legs, 2 have black feet, one has feathered legs. I am thinking they are pretty much a barnyard mix (definitely don’t seem to be Australorps) - but thought I would post and if there were any other thoughts. (Disregard the Buff Cochins in the background of some of the pics)

Looks like a bunch of Sapphire Gems.

I think there are several different varieties there. The ones with red/brown on the neck feathers/breasts are not Sapphire Gems, but maybe Rhode Island Blues or Production Blues. Any with green or yellowish legs are Sapphire Gems. Any with pinkish white at the bottoms of the feet instead of yellow could be blue Australorps.

TSC could have mixed them all up or it could have been the hatchery itself that sold them that way.
