I have a hen who seems to be losing feathers...

I have three hens and one seems to be losing tail feathers. Each day I clean the coop I find a bunch of feathers on the ground and my sister thinks that the other two hens are pecking her feathers out. I have not seen any pecking going on but this chicken does seem like the one to be bossed around by the other two. I see not open wounds on her and I am wondering if I should be worried or is this just usual molting?

You might read these two articles and show your sister the pictures. Without looking at your chickens, I am almost certain it is just molting.
