I learn from the BBC that chickens are to be kept indoors to create a Bird-Flu-Free-Zone. This prompts a little song we can all sing as we round up our chickens (if we have any):

Bring in your chickens!
It’s Indoor Poultry Week.
Pop your chicken on the couch
And pat its little beak.

Apparently we should also be on the lookout for dead or debilitated swans, and report any sightings to the police.
