Jason,
if they are young and you get them from a good breeder (Kammerflage?) they may already be accustomed to cup feeding. Unless they are older and/or WC, you probably won't have a problem getting them to use a cup. It's easy to set up. Put secure branches around and over the cup so they can easily shoot they will know that is the location they find food. Actually I had 3 cups in their enclosure so they thought they were hunting LOL! but they always seemed to go to the same one. I have some pix of my setup if you want me to email some to you. The FF were a big part of their diet.
I am not sure if John and Morgana cup feed or what success Kristen had and I am sure they will chime in soon.
Who are you getting them from? You have been on the forum long enough and went thru all the losses that Kristen and I suffered so I think you know that they are a bit tricky. I loved my little ones and if/when I get them again they would ONLY be cbb and probably from the Kammers. Again, hope I am helping
