On the subject of hen housing
I recently bought a chicken coop from http://www.benedictsfarm.com. I thought it might be of interest to note that it was extremely easy to set up and seems very hard wearing.
Their site also offers a wealth of information for beginners on where to buy chickens for example - http://www.benedictsfarm.com/pages/where-to-buy-chickens
Was very useful to someone who was completely new to the whole experience.
Hope this helps,
