we got 4 running loose in our garden any rats coming will get nailed by our feral tom cat.the hen house is on the path running round the side of our house and when i shut them in at night i just lift the feed hopper onto the roof of the hen house.i have 3 norfolk greys and a norfolk x light sussex i think.they peck around the garden scratch under the leylandi trees and seem fine i just put a water bowl down as well.the yolks are really yellow.
