Well, it’s been 5 days and for 3 of them at two different resorts the ducks are allowed in the pools. It’s ignored. Then, they poop in the pool and we all have to vacate because of swimming with duck poop and the diseases they carry. Can they just be shoo’d off for heavens sake. It’s disgusting to swim with them.
A large portion of Disney is a protected wildlife area and so the animals & birds & reptiles are protected. Disney has always allowed the birds & ducks in the parks, hotels and
even the pools. They tell guests not to feed them or engage with them so they might move on, but overall they seem to protect them.
In my thought process it is no different than swimming at the beach among all the fish and sea critters. But I get that it is a pool and that it is expected to be void of wildlife. BUT I think most "readings" you'll find do say that ducks in the pools are generally "allowed" by Disney and left alone. Yes a life guard might shoo them off (without violating their protective rights) but I think we all know they'll likely come right back so .... they likely don't bother.
I personally don't like "public" pools because of the humans leaving behind genetic material, at least I can see if the duck does poo and move away. And I'm more bothered by how clean or not the ride vehicles and other park seats/rails/handles are.
As to the human you speak of that is the daily pool poo-er, no they should not be allowed back because they know better, because they can read the signs and because they are not a protected species per se, and are visiting. Ducks live there. Ducks are doing what ducks do. Ducks are protected.
There is lots to get upset about at Disney ~ don't think this is one of them. If you must be evacuated from the pool to skim and shock it ... just get a snack, eat a meal, take a nap, explore the resort, join an activity elsewhere .... or go to a different pool as I think the resorts all have more than one.
