We have a flock of 15-18 swans on a large pond on our land, but the flock seems to be shrinking rather than reproducing. We think this is because predators - raccoons, possums, snakes, etc. -- are eating the eggs.

I don't know the exact breed but they are white with blue trimmed wings.

Can we build a raised nesting box they will use to build their nests. If so, can you recommend a desing.

Thanks.
