Hi there, My beautiful Khaki Campbell duck sat on, hatched and raised 14 ducklings about 2 years ago - what a proud Mum she was. Since then however, she has tried and tried to no avail. The eggs don't hatch - they just go rotten eventually and I have to destroy the nest. I leave her for about 8 weeks each time, just in case - but no - nothing. Is it possible that Mr Campbell is shooting blanks? Paula.
