Well here in Kent (Dartford/Swanley) I paid £11 for each of POL (Sussex Silver, Sussex Light, 2 black ones and a brown one...). The hen house was a shed from Wickes (£99) and the very secure covered run was made for about £150. The wire was free (off the tip). I thought a 20 foot run would be plenty big enough but the little darlings have now taken over the large green house. This runs along side one side of the run and is easily accessable by lifting up a pane of glass! I thought this would be a good idea for them to have additional space in the winter, rather than let them out of the 'secure' run to free range when I wasn't sure what time I'd be homefrom work.
The result - I now have 6 chooks who produce 5/6 eggs a day and are sold for £1 a box, no tomato plants or cucumber plants in the green house and because they are hybrids I gather (from reading this site) that they are unlikely to go broody so can't raise a few chicks to increase the flock and help meet the huge demand for eggs that I have from my neighbours.
But look on the bright side - I have 6 very pampered and well loved hens living in luxury with more room than they know what to do with, and an OH who if he reads this will go mad when he finds out the true cost ..... sorry Darling! XXX
