My current test is at Orthard Blue, I gave him 6 plum and then 1 pear and then 1 more plum and I got the feather message and stopped feeding at that point.
Based on how I think the system works, I should get Raptor Blue. It's possible that the 1 pear wasn't needed. After the 6 hours, I'm going to try and revert back to Orthard Blue and record my changes.
See you in 6 hours.
