Sounds like you will need to enlist Mrs ByBob to help with training.I would think genetics are playing a role.
The cup hand treat method is how I trained my previous 4 to eat peacefully together when their name was called. I just need to work with them. It's just harder with 6. I could control 4 and arrange them, etc. I can't keep 6 still long enough or dole out treats fast enough for them to wait their turn.
