The Penshurst is a new range of housing that has one major advantage over the other units we build, in that it has draft walls which afford the hens protection from the side winds. There is also a covered area at the front of the run for further bird protection and to keep their feed dry. A door in the side of the run helps when catching.All the triangle walls are fully removable including the central the pophole wall. There is a nest access hatch, (except the 402), set into the back door for egg collection, which does restrict the chances of a bird doing a 'runner' when you're trying to collect eggs. The nest and perching also dismantle to aid when cleaning. The nest does have night shutters but I must be honest, because the shutters are so low they are awkward to operate.
