I had not thought of interplanting tulips and daffs.
My thinking is ( a theory mind you ) it might work. I doubt deer would deliberatly shuffle thru daffs to get to tulips especially at this time of year when other "brouse" is available.
They seem to be opertunists and eat what they find rather than conciously go for a certain plant.
They have trail habits, and when they find something yummy growing in the trail area ,they eat.
Rabbits on the other hand will eat tulips no matter where you hide them.
