got a large red and I put him on a split wooden drying board and now can't get him off I thought about using air or a stick to try and break him free but did I do something wrong? how do I know it is dry? it has been on the board for 3 weeks and now seem dry at the tail and up the belly.

take the board by it by the sides and smack the nose on the floor, it will come off, it might take a couple of whacken's to loosen it. just don't smack the floor so hard you break the board. I use them adjustable boards for that reason. good luck. woody

if that doesnt work for you wrap the hide with wet towels it'll rehydrate enough to pull it lose the put belly board and put it back in and redry

Thats what belly wedges are for.
