No we have not gotten rain in a little over a week, and she is chewing the wood by her feed bin which is under roof. I have not seen her do this any other time than when she is eating. I board my horses so I am not out there all day but the days I do spend there I dont notice this except at meal time. I did not breed her just bought her 2 weeks ago so am watching her like a hawk right now to make sure she is coming along nicely and is happy and healthy. My other two boys do not crib and to the best of my knowledge her dam did not crib. If it gets worse will try to spray on the wood if I must but this is where they do eat so may cause some issues there.
