Is this story going to have a sad ending?

Hey, at least we skipped the silkies this round.

Which ones are the most likely to go broody first? Does that ever start a domino trend, or is it very hen specific?

True you escaped the silkies.
The Orpingtons will probably go first, followed by the Australorps, I think it will be a domino effect, as when weather conditions are suitable they will go broody together
