Thanks for the image. One issue I have is I'm not sure how old she/he is. I bought 6 assorted chicks 3-1/2 weeks ago but she/he was bigger than the rest the day we picked them up. I cannot pick her/him up with only 1 hand (my wife calls her the beast) and she has alot more feathers than your chick, she has very little chick fuzz on her.
I've been questioning the age of my chicks myself. I did not hatch them, but got them from a farm and I'm not sure they were all as old as I was told! Hopefully some more people can weigh in on this for you.
