Cord wood chicken coop? too much moisture?

So, I was thinking of building a cord wood chicken coop/ garden shed (separate but same structure). This would be mostly a winter coop and during summer they would have pasture and a summer house.. It would also be an occasional place for a broody hen to make more chicks. I have been looking in to cord wood for a few weeks now and am still in the early stages..
Really my main question and concern is moisture in the coop.. Obviously I will clean it out occasionally and droppings will not pile up too high.. But what I was wondering about is moisture. With hens indoors most of the time during the winter, and with water in there, and their breathing, damp flooring (dirt floor). Do any of you think I should worry about wood soaking in moisture, interior end of the wood molding, or rotting? If I decided to do it in cob instead of cement? These are all ideas options and issues swimming around in my head and I would love any input.. Thanks.

Good hat and boots... as the saying goes.

Mold wouldn't be the worst thing, chickens will have health problems spending time in damp places.

The ground around your shed/chicken house should be dry because of the roofs overhang, and so
should the soil inside. Deep bedding will help as well to absorb moisture and cover their droppings.
Build this building on a slight rise from the surrounding land. Make sure any water moving on or
under the ground toward your building is directed around it and away quickly with rock trenches.

If you are in a very wet place you may want to consider sealing your wood-motor on the outside with
resin of some sort.

You're going to build a shed that houses wood, tools/equipment and chickens, right?

Sounds like you will do well with the above reply, but look into getting or making an automatic door that lets them out in the morning and shuts them in at night. No getting up at 6AM for you.

Dry feet and a decent enough heat lamp will do your birds well. I personally don't keep chickens over the winter, I just use them for the summer months and eat the eggs and meat and call it a season.
