We have this coop : http://cgi.ebay.co.uk/8-x4-x-5ft-Po...054L-/290466116083?pt=UK_Pet_Supplies_Poultry Currently have 1 Rhode Island and 2 warrens but Id also love a silkie. So, have I got enough room for one, the ad says 8 birds which to me would be a little cosy to say the least. The Chickens do get let out into a 50m2 garden for 2-4 hours per day although we are fencing off a smaller area of about 12m2 for a more permanent space for them. SO, do I have room for chicken number 4??
