Sex linked cockerel or barred rock pullet?

[Nay117]

new chick mom here .. apologize in advance for sounding stupid or not knowing anything about chicken breeds! So I purchased 3 "jersey giants" from tractor supply .. clearly after 3 weeks of having them they are not. 2 I am now pretty confident (with your amazing help) are sex linked pullets. The other everyone suggested maybe a barred rock but now that I am being crazy and doing research I am wondering if she/he could be a sex linked cockerel? He/she is on smaller side (half size of my others but slightly bigger than bantams. I honestly have no clue. Margie's legs are black in front but more yellow in back with toes fading to little yellow. She started all black with white spot on head then slowly barred came on wings. I'm thinking 3.5-4 weeks? Thanks for any input!

I'm thinking BR pullet but time may change that.
