Need some gun dog training advice

I have recently introduced quail feathers to bumpers and my pup goes absolutely nuts when we train with them. She loves them. So much so, that I have a difficult time when I throw multiple marks and use the feathered bumper mixed in with other bumpers. She will mark and run to the bumper without feathers but won't pick it up because she can smell the feathers and wants that particular bumper, even if it 50 yards in the opposite direction. She just keeps hunting for it. I have a feeling its time to force fetch or either when training with the feathered bumper, just leave the others out of the mix. Opinions?
