The bottom line when building housing for waterfowl is the mess. Ducks are not house proud and do 'it' anywhere, anytime, all the time. So the Lenham Duck Houses have got removable side walls that when fully removed open the house right through. To clean out you can even use a shovel. The large access door allows geese to enter without dropping their heads, although they will stoop to get out, they are reluctant to use a low door. Full length ridge ventilation maintains healthy air circulation.
