As you can tell, I am cleaning up this "lean to" area on the side of my cellar to make room for my chickens. This was originally a 2 story building and this side was also closed in with a door so the block has never been sealed. Should I use a sealer, exterior paint or good old fashioned white wash? The floor could use some patch but not sure it I should just seal it or apply some vinyl flooring? This is the current coop. Kind of crappy looking because I made it fast due to someone giving me chickens when I hadn't planned on getting them until next spring. As you can tell, the open part of the building has electric and on the other side of the block wall is my water so it would be easy to install. The other side is my pump house and I have free gas so we keep a smaller gas heater in there in the winter to keep the water from freezing which is great because I have free gas. I am also assuming that a smidge of warmth will permiate through the block wall to help with the chickens so I will not be adding any extra heating source. It does have open rafters that we use for storing stuff like trapping supplies and I hang my black walnuts from there to dry. We have a real problem with black snake up there in the summer but I am not sure how to close it off or not close it off and still protect the chickens.
