Mumma hen is seriously digging up the yard. She is almost manic about it. Not sure what is going on? Could it be that she doesn't have enough room for a dust bath? I wouldn't think so! Is it anxiety related? I am having to clean out their water and refill 4 or 5 times a day, no matter what/where I put it, she fills it with dirt. She is so panicky at the moment!
