I hate to be discouraging, but taking her away from a familiar place, WITHOUT her own calf, is not a good recipe for success. Most cows will tolerate other calves nursing if they have their own. Try only letting the calf she is used to from the other farm, in on her while she is eating. Then if she will take it, try putting the two calves in on her. But don't leave them with her except for feeding for a couple of "milkings". The one you weaned may very well go on her as soon as it sees other calves sucking, if it hasn't been weaned very long.
Don't know anything about the "orphan calf" stuff, some cheap perfume sprayed on her nose and the calves backsides will often confuse their sense of smell, to accepting a new calf. If your bottle calf was very aggressive, it might go on her from the back without much encouragement. But when you do bring her in for grain, and let the calves on her, she needs to be in a stanchion or head catch so she can't turn around and smell the calf right off or move away from it. If there is enough pressure on her udder, she might let it suck. But again, not getting her calf with her, and then moving her away from all that is familiar, is a couple of strikes.....
Hobbles on her back legs will prevent her from kicking the snot out of them as she won't be able to raise a back leg and kick hard without pulling the other leg out from under her. Some cows this works with...
