It's really fascinating watching your muscovy ducks's antics and the fact that they don't seem to be at all camera shy... Do you think they might make good use of a couple of low steps or similar to get into their various bathing pools, especially the larger pink one they love using. I wondered if they then could perhaps use the top step as a small platform to stand on for subsequent preening rather than trying to make use of the pool's narrow edge which is a bit of a balancing act for them. Just a thought...
