The new coop was safe enough for the girls to sleep in last night. We have 11 hens and the new coop is 8x14. Temporary roosts they've been using during the transition included. The coop is inside part of our 16x24 workshop and that's where they've been staying during the transition. This morning it's a disgusting mess! Most didn't sleep on the roosts and clearly stayed up way too late having a poop party in their much larger space. I know there will be an adjustment time. The concrete floor is mostly covered with the same interlocking childrens play mats covered with pine shavings that they've been staying on during the transition. They've been in the temporary coop since Thanksgiving. What do we cover the floor with temporarily to minimize the mess? Hay?
