A cage that size for 8 chickens is FAR TOO SMALL. Don't you have a garden where you can put a chicken house and a run for them? Australorps grow quite big. I must admit, I've never heard of anyone keeping chickens in a cage before (apart from a crazy French woman I once met, who had a pet Light Sussex cockerel in a cage in the house - but even she let the thing out during the day, to run round the living room!!), most of us have them in runs, not tiny cages. Chickens need space to scratch around and do what comes naturally to them. What do you think Hugh Fearnley-Whittingstall has been making all the fuss over battery chickens for???
