John my experience last year growing comfrey from seed was that although I got pretty good germination, the young seedlings were fragile and indeed got browsed to death by everything, including small rodents that climbed into my pots. I only had two plants survive to the fall, and one of those was just a four-inch spear (the other had half a dozen full sized leaves by first frost.
For me the true glory of these plants waited until the second year. The larger plant took off early this spring, exploded out of its tire planter, and is now two and a half feet tall and has already flowered. The smaller plant is still in its pot but it's 18" tall and flowering.
I think you're on the right track to buy some crowns for this year. But if you do get any seedlings, baby them along and don't despair if they stay tiny the first year.
