IV'E SEEN IT ALL NOW--

--Well I thought I had, the first thing I noticed was a bottle had been thrown into the nest, I was standing their and the swan stood up reaveling the four eggs, she then entered the water and had a bit of nookie with her mate before going back to the nest to squat down on the eggs again, so there could be another batch of eggs in a couple of months time, if no more bottles are thrown at the nest.
