DO give the oatmeal another run...and I know you're not huge on raw, but try it, maybe just this once with ground turkey!? See how she does- or just make a tiny batch of it and see how she does. I put fresh chopped carrots & a handful of frozen peas in mine. My dogs LOVED it, and I can already tell a difference in them. They were tired for a couple days, just like you said they would be, and I'm sure there may be a few more tired days
I have already noticed that they get FULL eating the same amount of this type of food. They stop/slow down eating sooner. They also take TIME to eat their food-probably about 5-10 minutes, when Emma used to gobble up her food in less than one minute. They don't BEG like they used to-because they're satisfied after a meal, and it holds them until their next!
