Thank goodness this is not my neighbour .....we have around 80 hens, 20 bantams, and God knows how many cockerels of various shapes and sizes. Have two barn conversions and a house close by the field, but so far, no one has moaned, and they all buy my eggs from the gate. Maybe they think if they moved my hens, then no fresh eggs
I know a friend of mine had a pond in her garden and wanted to keep three ducks. She checked her deeds, and for some reason hens and ducks were not permitted - not sure why, it was privately owned by her, but there you go.
