I decided to just give it a try. Since three of them wouldn't touch their raw meal, and I didn't want them to go without at least a small meal, I went to the store on my way home from work. I picked up one can of food that I know they eat, and some catnip.
When I got home I seperated the three that were apprehensive. Silver, Audrey and MissMouse. Then I mixed a little catnip on the raw food. This at least got them to touch the food and try to eat it. When they stopped showing interest in the catnip/rawfood, I got out the can....they knew what that smell was!! So I took a butter pat amount of canned food on a knife and smeared it well into the raw, then I took the same amount and smeared it across the top.
This method seems to work on the stubborn three. They were still a bit unsure of the large chunks, but they cleaned their plated. MissMouse, who is accustomed to letting her 1/4c. of kibble sit all night as she grazes it, didn't eat it all in one sitting, but she did eat it all by later in the night. She was the one I was worried most about being a hard-case. She is the oldest, at 4, and doesn't even like treats...just her kibble (can we only ever fed when administering meds).
