Hi and welcome to the forum from sunny Shropshire. If you are not a crafter yourself, you may be able to sell the fleeces to local spinners and felters. Generally speaking, fleeces aren't worth much but being a primitive breed makes them more appealing to spinners. If you''re not already a member of Ravelry, an on line forum for anything woolie, I would recommend joining and looking for a market among the spinning groups. Most of the groups are American but there are a number for the UK.
