A neighbour of mine complained when I got chickens. Said 'you can't do that, there's a restrictive covenant'.
So I checked my deeds, and there was no such thing. Checked his, and it was indeed there. We live right next-door in identical houses built at the same time by the same developer and all our paperwork was identical word for word except the fact he couldn't keep poultry.
Work that out if you can...
