Wood floors just require slightly different handling.
Bed deep. Don’t use boriums if possible…they chew up wood like termites. When you pick them daily, sweep the bedding to the outside edges and bank it, leaving the center bare. Leave it this way until you turn the horses in again, then just knock the banks down into the center again. This allows the wood to dry.
Downsides: no boriums or studs if you’re in an ice-prone area. No mats. They’re a bit loud if you have a stall walker…sounds like Lord Of The Dance guy, LOL!
Upsides: very easy to maintain, just check each board twice a year for any signs of rot. When one shows rot, yank off that one board and replace it with a new one.
One place I boarded had gorgeous wood floors in an awesome old style barn. The dirt floor underneath was almost 3’ lower. Only problem for us was my mare was a stall walker…and kept the BO awake all the way up in his house that was 200’ away! :eek: :lol:
