i agree with Foxy, this coop is far too small for more than two birds of any size. Until you've kept chickens, you probably don't realise how much they poo, and if you have them in a small space, things get extremely messy very fast, especially over the winter. Letting them out in the garden is good, if you don't mind them scratching around and making a mudbath of it in winter especially, but you need to be very sure it's safe not only against foxes but also cats if you want small bantams. i think a better bet is to go for a freestanding coop in an enclosed run, giving a minimum of 2 sq. metres of run per bird. You and the birds can move around more easily in a run like this, and as it's not going to be very big (6 sq.metres for 3 birds) you may be able to roof it to provide better shelter. You still have the option of letting them out when you're around and the weather's nice. A free standing coop will be easier to keep clean, especially if you get plastic instead of wood, which will also last for ever without treatment or leakage. Have a look at Green Frog Small Chicken Lodge, which would be good for up to 3-4 bantams or 2-3 larger hens. See http://rarebreedpoultry.webs.com/ecofriendlyhouses.htm
