My hubby is about to break ground on my new barn. It's not huge, but will have a milk room (goat) and 2 stalls (goat) on one side, and a tack room or brooding room on the other side plus a large chicken coop (chickens free-range during the day). My bunny cages will be either mounted under the covered area he is making on the back of the barn, or they will have their own covered area separate from the main barn. I need some advice. I know I'm going to concrete my milk room, and I will concrete the other room if it is going to be for feed (not if it's going to be for a brooder). Dh wants to concrete down the whole middle aisle and the covered area in the front (6x24). Would you do this? Is it hard to keep the concrete clean if the animals have access to that area? I know we can blow off goat poops, but what about urine? Any suggestions about this? I just don't want to make a bad decision, as I'm sure this will be the last barn built for a WHILE!! Thanks for any help.
