Ooh chicken house porn. Do you know how big the actual house is in the first one? Eglu looks fab but lots of dosh.
Mine live in a converted dog kennel. You could always buy a cheap shed from B&Q and attach a run (avoid felt roof because of red mite). A shed would give you the option of having more chooks if you like keeping them. My DH stuck a perch in the dog kennel for them and they have a washing up bowl with straw in for a nesting box! They are happy as larry (whoever he is).
I have a cube and I love it, takes about 5mins a day to clean out and is totally fox proof. is however very expensive. And the fresh eggs are worth every penny, this week I have no money, so I am selling eggs to pay for playgroup and things.
I have an Eglu cube and a Forsham arks Broughton one (9 chooks). I do really like the Eglu cube for ease of cleaning but, there is no way of closing off the nesting area at night; consequently one of my chickens always sleeps in there (and shits in there)..thus crappy covered straw needs to be removed from that area every morning unless I want my eggs to be streaked with sh*t.
