Several horses are living freely in the fields around the campsite. To avoid the accumulation of excrement and at the same time utilise this resource as fertilizer, we created a mobile hen house. The chicken scatter the organic matter all over the field which makes a natural fertiliser for the ground. At the same time, the hens eat all types of insects which help to prevent bug invasions. The hen house can move from field to field depending on where it is needed. During the night the chickens go inside to sleep, like in a traditional hen house.
