Amorphous Girl Boss
How old is she? Did you discourage her aggression towards them in the past? I know it seems mean but I've always told my LGDs they're good girls for snarling and snapping at the goats (within reason) over their food. I do have one who will just go hungry, he's overly nurturing and will let anything take his food straight from his mouth, luckily he free feeds and only lives with other dogs.
If this were my situation I would feed them all at the same time so the turkeys have their own food to worry about, train the dog to eat on command and I would supervise feedings, take away any leftovers after she's had enough time to eat, she may be hungry occasionally in the beginning but she really should figure this out after a while and finish her food in a timely manner. For a period of time one of my LGDs wouldn't eat all of her food and would let the goats take it, I had to be pretty firm with her and spritz the goats for eating her food, I had to make her stand there and eat it, I wasn't mean but I was not going to budge and when she was finished I took it away, she finishes her food now and doesn't share.
