Aha.....you need a pair of ducks (or more) in the garden to eat the
snails and slugs. Ducks are lovely people, very friendly and she will
reward you every day with a nice fresh egg.

We let our ducks (two boys and a girl, guess they just have
to share) have the run of the backyard. We have no snails and
just a few slugs. But we don't get an egg a day. These are
appleyards and they seem to be very seasonal in their laying.
Then when she does lay, the crows usually get it.

We plan to get a couple of chooks once I have built a yard.
Ducks are pretty garden friendly, but chooks will turn the
garden into a desolation.
