Hey everyone, I have a big shed that of six hens and one rooster. we plan to add around four more chicks to the group. We would use this shed as their coops, giving them a large ammount of space to eat, drink, relax, and lay eggs. The only problem about the shed is its horrible smell. It has a very musty smell that has been around since we moved in last year, and I dont know if this would be dangerous to our beloved flock. For comparison, it smells like a musty unfinished basement. I do not see any visible ventilation in it. It certainly needs a touch up but once it it finished I am certain it will make a great home for them. I will provide images as well to show you the ventilation and such. My question is this: Is my shed safe for my chickens and if it is not how can I make it so it is? How do I get rid of this odor?
