Hi Leslie,
If your daffodils are as densely packed as you say they are, they might actually benefit from a little more leg room! Wait until after they finish blooming and their leaves have mostly turned yellow and brown to dig them up. Bulbs are generally quite easy to divide: just carefully peel them apart from one another—leaving any remaining leaves intact and attached—and space them out as you like (4–5 inches apart, minimum). Plant them at the same depth that they are now and they should be happy.
