Urban Chickens in London

Natalie Steed has posted on urban chickens in London. http://nataliesteed-lcc.blogspot.com/While I'm there this week, I want to meet up with her, and to investigate the urban chicken culture there. Are there organizations like MadCity Chicks (in Madison Wisconsin) or the Seattle and Portland chicken movements? Natalie writes about the Suffolk avian flu outbreak: I need to learn what kind of flu it was--low path I presume, but what was its type? And I need to talk to poultry people in London, Oxford and the environs.
