Question for Dr. Joe on Cydectin

Is there a trick to getting the deer to eat the cydectin sheep drench? I sprayed it on to some Purina AntlerMax Deer Chow 300, the sweet feed, that they normally fight over to eat and they will not touch it. I even taped off the regular protein feeder and in one night, they chewed off the tape to get to the regular protein. Any ideas?



Thanks for any advice!
