Chickens, geese, turkeys and ducks are allowed on our private site and whilst I have no objections personally there are problems with:
a] noise to the surrounding houses from cockerels in particular,
b] some owners have no consideration for others and do not ensure that the runs are secure or that the birds wings are clipped. The birds escape and eat other peoples crops.
c] some owners have no consideration for the birds and leave them for days without attention. Some are regularly left out at night and are at the mercy of marauding foxes. Deaths and mutilations from foxes are surprisingly common.
With bees inquisitive kids would be my main concern although I would think that the ever increasing problem of insurance is the crux of the matter. Any intruders seem to have the right to claim in the event of injury.
