Need some advice. We have bought a wooden chicken coop its all built and ready to go hut we dont have the birds yet. It has a wooden roof no felt. Last night we had heavy rain do this morning ds went to check his pretend chickens and when we opened the door to look inside it was all damp through on one side. This coop was not cheap it was over £700 it does have a guarentee but am i right in thinking it should not be getting wet inside? There was nothing in the build instructions about the wood needing treated. We are in a part of Scotland where it rains 80% of the year so this is not good. Do other wooden coops with wooden roofs let in water?
