If you are referring to the fern known as Ostrich fern, Matteuccia struthiopteris, they should transplant fine. Do some research based on the latin name provided here.

I just translated a bunch of ferns (from one site in the ground to anther). No problems. I would suggest that you do it when the weather is cool and humid (not on a very warm or windy day). Also try to do either early in the day or in the early evening. Be sure to mulch some and water them in. Good luck!
