Generally speaking Hazel do not root from cuttings, very easily. they are usually grafted if culinary types or grown from Nuts if the hedging forms.
Easy enough from nut kernels. Break open a nut, extract the kernel and sow in ordinary potting compost and leave for the winter. Protect from vermin.
The ones which grow from squirrel plantings germinate slowly as the hard shell has to rot away first.
Just bury the nut, it works for squirrels
I've never taken the shell off any nut I've sown.
Leaving them outside through winter is the really important bit
