Our coop is a double-axle utility trailer that was converted to house up to 300 broilers. We only have 20 in there. The floor is wire, so the poop falls thru, with a little raking. But the poop doesn't dry well in winter. A few of our birds have respiratory issues, we're having to treat them, so I decided to close off the floor for the winter. 4 sheets of OSB, a sawzall, a bale of pine shavings, and it's done. I put in the water heater too. Just in time. It was 68° when I got the OSB and 41° an hour later when I started cutting. Now we have 31° and freezing rain. Weatherman says we're visiting the 20s soon. If it's that cold in Texas, y'all up north are probably shivering your timbers, as it were. I bet our chickens are happy now. If only they could talk.
