Flushed by my allotment success, I've been looking at a high-tech chicken coop called an eglu, which is specifically designed for small urban gardens. They are quite expensive, though, so on a whim I checked on ebay - and there was one up for sale in Birmingham with only a few minutes left on the auction. Of course I couldn't resist bidding...and I won!
Then I was left with the problem of breaking the news to Rich - of course he was very sweet about it, albeit with much mock groaning and burying of face in hands :)
