We are planning on building a new coop and run, so I have been looking at coop designs. I really like some that I have seen, however, I'm concerned about rain/mud issues here in the Pacific NW. We thought our current coop and run would stay mud-free through the winter, but we thought wrong. I think the coop itself would have stayed mud-free had we built a wood floor and covered it with linoleum and shavings (was designed as a shelter for calves and has a dirt floor). The run is made out of chainlink dog run panels and covered with metal roofing. Are there any coop/run combos that would work well in our wet area? I'm thinking that an enclosed and covered run will be the best option. I'm thinking sand or pea gravel would also help. I'm really leaning towards doing some type of gutter system as well. Maybe someone has some suggestions on what works well in such a wet climate. I should also add that we're looking for something for about 20-25 hens. Any suggestions would be appreciated.
