Black Chickens... Breed help please!

[NewMomma2017]

Hello,
We were given some broody hens that were laying on some eggs. I have no idea what breed they are. Any ideas?
There feathers are missing on there backs. Is this from a roo you think or bugs!?!

Thanks BYC Family!!

You may as well check what color the bottoms of their feet are while you're at it.
