27 weeks.
She and Pong were supposed to be a matched set, so to speak (which explains the goofy names LoL). "uh, toss in a couple of Australorps too I guess" when I had to make an emergency chick purchase at tsc.
About 6-7 weeks I noticed their feet were noticably no longer the same coloring, okay what the hay, closer inspection on feet and little combs, a bit of research, someone is not who they claim to be!
Pong is an Australorp but Ping is a Jersey Giant

, thanks tsc!

Oddly enough, Pong is still the bigger one, keep waiting for that to change!
