same here - they mostly play with each other - I've seen them chase the
occasional chicken as well hihi
we do however dump just cut branches and tree stumps in their (dirt)
paddocks so that they can eat the bark ( especially birch & hazel trees) -
keeps them buzy for ages and afterwards they look really funny with green marks
on their faces.
only nuisance is to cut the trees by hand saw rather than chainsaw to avoid
petrol etc. deposits on them
