They look nice and plump and healthy, I'd replant them. They might be hyacinths but different types of bulbs can look very similar.

They look nice and healthy. Definitely replant them. They look familiar, but I cannot say for certain. I agree that they look like hyacinths, but there are so many kinds and the differences are subtle.

I agee with the others- replant them; they may not have flowered as yet if they were "forced" indoors prior to being planted outside. Give them some time.
