Could I have a loner?

My chicks are finally in the coop now at seven weeks. They are having a blast! Trying to fly, playing, getting on thier roost, learning to pick through veggie scraps and scratching for grain.
One problem tho..I think. One of my barred rocks has turned anti social, when the rest of the chicks are together she stays alone either feeding or sitting.
Should I be worried? She seems healthy, eats like a pig, same size as her sister and the other birds, does everything they do just by herself.

I have. Hen who is acting that way. She stays by herself under the porch most of the time. She was not that way until I put 2 older buff orphingtons with the 3 hens I originally purchased. I look forward to hearing what others say to try to figure out if my hen is sick or what is wrong
