Wood chewing(NOT the same as cribbing/wind sucking) can be caused from a few things.
If the wood chewing came about this time of year, it's fairly normal due to lack of grazing. They will seek wood to chew, peel bark off of trees and branches. Once the grass comes on it'll resolve.
If the wood chewing has been ongoing, it can be from boredom (as already mentioned) especially if they are in a smaller area with no grazing and no free choice hay.
This also leads into another cause, lack of fiber. If they aren't getting enough fiber from grazing or hay they will chew wood.
Another cause is they could be lacking a vitamin that the wood could be providing. Much like horses that'll eat dirt.
