Stunted growth chicken

[ACW2013]

I have a gold laced chick that was a hatched around early- mid may (not by me). I have a lot of birds so I never paid much attention to this particular chick until recently when I started thinking "I've had this chick awhile and I swear it's not growing". It's a healthy bird, good appetite and very active but I feel that it should be bigger for a 2+ month old chick. I think she's a hen ( I named it Tiny Tim) and I saw a full size rooster on it) and thoughts? Health considerations? All birds eat mixed flock rations and free range. The pic has a chocolate orpington the same age

Could she possibly be a bantam?

She's supposed to be standard but I guess anything is possible. She was given to me by a friend. I guess only time will tell. The only trauma was a near drowning when she was a chick but I got her dried and warmed up and she recovered fairly quick.
