We have a natural pond in our front garden which for the past year has been home to a pair of moorhens - last year they had two broods, though the first lot disappeared mysteriously. We live down a quiet lane so fairly sure that they were not run over, but the second brood followed soon after so we persuaded ourselves that they had simply left home. The parents left for a short while during the winter but have been back now for a few months and are quite happy to wander round our back garden picking up the birdseed that falls out of the feeders - other than that we do not feed them. In the last few weeks there has been a pair of ducks who turn up randomly and are 'squatting' in the nests that the moorhens build - they generally have 2 or 3, guessing that they make some decoys as well as the actual incubating nest. Anyway, my main worry is that the ducks will scare away the moorhens, but so far they seem to ignore each other, again we are not putting out any food. We have several large koi and who knows how many crested newts and a healthy population of frogs as well so it's quite a little eco system going on out there. We rarely feed the fish but so far everyone seems to be OK and we've decided to leave them alone as much as possible. We had a pheasant hen that used to come into the kitchen looking for food and I don't think I could cope with a brood of ducklings!
