those pieces are probably pretty short and small diameter? if you want to try it, cut them oversize(like 1" thick slabs),seal the ends, then tuck them away inside your house where they can dry. good idea to have em with some space between each piece(stickered) and off of any surface.
check em in a few months to see how theyre doing. it is possible to kiln dry using an oven BUT its necessary to understand how. i didnt know how at first. ended up with some really nice walnut that case hardened BAD along with trapping internal stresses that came out when machining, then turned into high dollar kindling.
