We got two guinea hens and two mallards. They are still living inside for now, but they get outside time during the day. We put up a pool for the duckies and all was well until the guineas decided they wanted to swim too. In their case swimming resembles drowning more than swimming. They were well supervised so nothing happened, I rescued the little nutters only to have them continue to try and fail to swim with the ducks! Are they doing this because they have been raised together??? Did I do something wrong?
