I was wondering if anyone had any tips for maintaining the ground in our run? We have 6 chickens that spend time in the run. Ive raked it out at times and put shavings or hay down, it has a dirt floor. The temperature here now is about 35 degrees average and the ground often seems damp. We have rain and snow. The chickens frequently get soiled feet from the run ground despite the maintenance Ive done. Any ideas?
