Terri, have your Daffodil bulbs started rooting? I've been doing a lot of digging the last few days, and when I unearth Daffs I'm seeing root growth. If they're rooting, they've broken dormancy and should get back in the ground ASAP. Otherwise, no hurry.
Mary, I have noticed the same thing about bulb size when I divide Daffs- my blooming sized bulbs are less than half the size of those I originally planted. They're perfectly fine. I believe it's because conditions in Holland are perfect for encouraging plants to produce large bulbs (soft, sandy soil), and they're never allowed to become crowded when under commercial cultivation.
While those big bulbs are impressive, I wish new Daffodil bulbs were smaller- it would make them so much easier to plant! LOL
