Rolanberry Red should be about two steps from Blood Red using Berries.
I can't say how many you'll need. However, I'm fairly certain using berries will produce this:
Blood Red > Dalamud Red > Rolanberry Red.
If you do it in two 6hr sessions (one session of berries until you get "new feathers", stop, another sessions of berries until "new feathers", stop), you should hit it with a very good chance. But if you don't, let us know what you get!
