Heheheh....
We're in our normal 1 week Tucson Spring: 70's last week, 90+ this week with 100+ after.
Our hens quite literally, shut down until they acclimate. We're getting 12+ eggs now but I anticipate about half that (at best) for the next month until we get up to full temps. Once the 100's settle in and the box fan goes into the coop, everyone is right as rain.
I would probably be a little upset if I was wearing a heavy feather coat and pumping out footballs from my rear end when there was a major temp change! So yes, they will be discontented, and then acclimate.
