Over the weekend I moved the chickens into the new coop.
Three more nest boxes and lots more floor space make it very nice. The most time consuming part of getting it ready was the insulation, but much easier to do it while empty. I'm going to move over the roosting bars from the old coop yet. Otherwise I'm happy with it.
The second night after the switch I had two hens who insisted on getting in their old digs so I let them in then carried them to join the others. Tonight there was just one stubborn hen who got the special treatment. All are healthy.
