sounds like it would be a good thing to try, but having put down concrete this year for our goats after scald and having to trim feet every week, i would try not to be put off too much by concrete and think of the huge benefits...since putting it down and moving them in 5 weeks ago, no problems at all, and they are sooo happy.....just thought its an expensive but very useful thing to do
let us know how the wood chip goes, it sounds like a good choice of alternatives!!
