The tulips follow the same story, but tend to be a little more sensitive to this pruning.

This is the normal time to start seeing this type of growth. Cutting living tissue is a HUGE no-no with daffodils. It is likely that many will die, but some will return. They will likely not flower this year, and possibly next, since all of that energy spent growing the new growth has been cut off. Without leaves it will not be able to complete photosynthesis and will then not be able to gather energy to produce.
In the future, let these grow without any help. They are well adapted to much, much colder climates than zone 7. This is why they are growing now. It is very mild weather to them, and continues to be "mild" even down into the 20's.
