Taprock, because the hawk is picking off your bantams I suspect it's a small one, perhaps a sharp shinned hawk and so is taking the easiest. A red tail I would think would have no problem going for whatever presents itself. If this is the case unless you lock up your bantams it's going to take one after the other till they're gone. I suppose any other larger hawk may also grab the smallest first and then go on to larger birds as they present themselves.
Whenever I notice hawks or eagles flying in my area no one gets to free range for days (my runs are covered) until the hawks go off to find more readily available food. They'll just hang around as long as they are successful.
