As cute as that girl is we need a couple of better photos of that chicken. One a close-up of the head showing comb and wattles. Another one or two showing the body. Of interest are how thick the legs re, a good profile of the tail, a shot showing the chicken standing so we can see posture, and maybe saddle and hackle feathers.
At four months, sex should be pretty clear. Looking at the legs I think pullet but I just can't see the chicken well enough to be sure.
if it is a true red sex link that is a pullet, but there have been instances where things get mixed up at the feed store. Some employees are much better than others in understanding what is going on. It is always possible that you got a "red" chicken, not a true red sex link.
