Can anyone recommend a good, practical book on keeping hens. I currently have two; 'Hens in the Garden, Eggs in the Kitchen', which is a bit basic and 'Living with Chickens' which is a bit American. These seem to be the only two the local Waterstones stock, and WH Smith don't seem to stock any at all, so I'm going to have to order something and as I hate buying books without having a good look first I'd be grateful for any suggestions.
