Hello!! About once-twice a month we go out to the chicken runs which are both attached to the coops to turn over the dirt and add in new dirt as we go. The question is, as we turn the dirt "of course with the help of our birds " we both notice a horrible smell of ammonia coming from the dirt itself. Is there any way to help with that smell by adding lime in with the dirt? We turn the dirt over and take some out to add in a bit of new dirt so the chickens are not walking in there poop and also to have fresh dirt to scratch in. The actual coop itself is cleaned regularly and we have never noticed a horrible moldy/ammonia smell from the coops only from the dirt once it has been turned. The first coop and run houses 2 Lavender Orpington Hens, a English Splash Hen, and One Lavender Rooster. The dimensions of the "Large Run" is 16x20. The second coop and run houses 2 Chocolate Orpinton Bantam hens and the dimension of the run is 4x8. Any advise is greatly appreciated by us and the chickens!! Thank You!
