It's Daffodil and Tulip season, can anyone answer a couple of questions about them?

I planted Daffodil bulbs many years ago in several areas. Oddly, Daffodils came up this year in areas that I never planted bulbs. How can this be? I mean, if Daffodils had seeds that would make sense but how can bulbs spread from one place to another? Also, my tulips are coming up looking horrible. I put Deer Away spray on them (rabbits and deer love our tulips but our luckily, not attracted to daffodils) and it seems like it damaged the leaves, is that possible? I thought the ingredients were natural. What is the best way to keep deer and rabbits away from tulips other than sprays? I don't want to have to fence them in, it's not very attractive! Thanks for any info.!!! I just love spring and I LOVE all the different varities of daffodils and tulips they've came up with over the years, don't you?

Ground animals could have dug up the bulbs and moved them over the years (squirrels for example) Try cayenne pepper sprinkled on the flowers as a repelant.
