Hi all, I live in Oregon and the rains have begun to set it. My chicken coop was surrounded by fresh green grass, but after the long summer, they grass is gone and all that remains is muddy hay. I would like to replace this with something. My birds don't seem to like sand all that much. I use sand IN the coop and they won't even lay down on it. I have to put pine shavings over the top of the sand to get them to relax. I don't think they would like it much outside in the elements much better. I have hay, but heard it gets moldy in the wet weather. I've heard that ceder chips are toxic ( http://www.ratfanclub.org/litters.html ). I don't want them standing around in a mud bath and I don't want to have to walk through mud every day to collect eggs. What do you suggest??? I have a 30' by 10' run. THANK YOU!!!
