Thanks for the sharing. There are few interesting thoughts which came to my mind:

1. The female ducks being forced this way by so many drakes , is this similar in the wild? or is this a phenomenon of the ducks in captivity?

2. The drakes vs swan. The swan is mated for life and is mild in their mating as opposite to ducks. The intelligent design , just pondering why t is made this way.

3. Need to appreciate the intelligent design, wherein the penis of drakes are coiled and stored in sac and are unleashed such that in water the sperms are not lost while mating.
