the old coop that i had on my property when i got it, needs some new siding, as it has some holes in it. the previous owners used 3/8 in plywood and some other wood strips to make the siding look like board/batton, it was never painted until i got there, but over the years the ply wood has started to rot on the north side, and the rest has seen better days as well. i was planning on using some pressure treated plywood for the north side and just regular plywood for the rest then put on some batten strips to make it look just like it is now, i'm trying to do it as low cost as possible. i do have some board /batten that i think will cover the south side left over from another project. also i'm not planning to remove the old plywood just the trim/batten and just side right over the exsisting plywood. thanks for any ideas,jim
