If you feed it 1 of every fruit randomly there is a chance you are simply going around in circles and gaining nothing.

If you like - I happen to have a little data about getting him Regal Purple from Default

Desert yellow
3 apple = millicorn yellow
8 apple = pumpkin orange
3 berry = sunset orange
6 berry = blood red
5 berry = regal purple

Every step here gave only 1 'new feathers' message - so the number of fruit needed might vary a little.
If you wanted to just use a lemon - there is that.
