So last month I purchased 4 chickens from tractor supply. I know what the other 3 chickens are ( 1 brown isa and 2 Brahmas) but as for the smallest chicken I have no clue I asked the store about the breed but they had no clue. When I bought the chicken it’s feet were yellowish-orange and now they are black. I’ve added a picture of the chicken. Thanks for any help .
