identity

Hey guys, I’m making this thread for @cluckmecoop7 because her internet isn’t working. So, she bought 10 buff orpingtons online and picked them up last week. The hatchery sent a free bonus chick, and it was white instead of yellow like the others. Now she is suspicious it is a meat bird because...

can someone please help me identify this bird???? Its almost 5 to 6 months old....

I am incubating for the first time and ordered 12 mixed eggs online unfortunately only 11 arrive intact. My question is can anybody identify what breed of chicken will hatch from these eggs?
