Now you know why it's called a Pecking Order. She is being knocked down a peg or two and yes, they will kill off a bird who shows signs of weakness, illness, or generally just not fit.
If she seemed to rebound after treatment for worms and antibiotic you should continue with same. Wazine needs to be for several days - check instructions on bottle. You can then wait a week or two and treat with a stronger parasite med, like Ivermectin which kills off almost all parasites. In the meantime, put her in a kenell/cage inside the coop so that the others can see/hear her so that once she's better and stronger she can be released and not be a stranger to them. They will forget one another rather quickly if you separate them and then will not allow them back into the flock regardless of their standing before the illness. Also, isolation causes stress to the sick one. I find they do much better if kept in the coop with their flock - in a cage or dog kennel.
