Hopping chicken

Hi there,
I'm having a newbie panic here,
Sam one of our silkies took to her bed for 24 hours, after reading various posts here, we decided that she was broody and decided that the best course of action was to turf her out of the coop.
Now here's the problem, she initially decided just to sit where we put her but when we approached her she got up and hopped off on one leg, this is the dilemma, has she hurt herself(hence the roosting) or has she simply got a "dead-leg" from sitting on it for too long.
She keeps stretching  the leg but doesn't seem to want to put any weight on it
Any ideas/advice ?  
Thanks

(it's now the next morning by the way)We locked the girls out of the coop, just in case it was the broody thing, but she's now occasionally putting weight on the leg, but also standing on one leg, limping, walking o.k,-all in all doesn't seem too happy about using the leg, but eating ok, having the occasional scratch, drinking o.k -help I'm confused

Im no expert but sounds as she has damaged her leg to me 

panicing shows you care about your girls 
glad she is better and good luck with the hatching
