I haven't used that particular brand of dehydrated raw but am familiar with Wysong Archetype and Stella and Chewy's, which are similar. Brody eats them when traveling or if I need a quick meal and since it is ultra concentrated I only feed a few bites. I haven't weighed it out to give you the exact amount but probably the size of 3 dice?
1/2 to one cup sounds like a huge amount to me.
Since you are using it as a supplement with the other ingredients, chicken, etc. then I would start with a very small amount and then increase it if she seems super hungry or you can start to see ribs. Go by what she looks/feels like. You should be able to feel her ribs with a slight padding over them. Backbone and ribs should not be prominent. Energy should be high.
