Mark, from what I've seen, confusion is the default state for chickens.

I understand that Britain went onto double daylight savings during WWII, two hours forward. I also understand that it saves a noticeable amount of power, making industrial workers go to bed earlier.

Here, the people who complain loudest are dairy farmers, because the milk-truck comes earlier, and they have to wake the cows up earlier. Why the issue them with wristwatches is beyond me!
