Can you keep ducks in your garden within the North Circular in London?

We have a massive slug problem in the garden of our house in suburban brent (NW London) and my girlfriends mum surguested getting a duck. We have enough room, it's just unclear from the research I've done whether there are any laws against it?

You would need to check your Local Bylaws with the council but I can't see any reason why not! Ducks are certainly less intrusive than a lot of dogs! Don;t have just one - get two!
Reply:ask your mayor,but i,m sure you can keep ducks,are you sure you are,nt stocking up for christmas.
Reply:I think you might find that you have more problems with what comes out of the rear end of the duck than you do with the slugs.

They are really messy.
Reply:it's the season for slugs you know, all garden have it. Put som ebeer in a big container and they will soon disappear.
Reply:Stick a can of opened beer in it.
Reply:Its best to check with your local council.
Reply:It shouldn't be a problem but you'd have to do a lot of research into keeping them! Will you need a pond?! A friend of mine has always kept geese (they're wonderful guard animals!) and no-one has ever said anything about that.
