Sadly, there's probably more to the story than your seeing. One, if they think that they are all drakes, they obviously don't know anything about ducks. Two, look at the age. These are Perkins. Meat ducks that is sold at TSC. Look at it from this point of view: Person walks into TSC because Person needs something from there. Hears cute little quacks. Goes over to sound and falls in love with what Person sees. "Aww... Cute! Come home with me cute creatures!" Person thinks. Buys and brings home with no experience beforehand. Ducklings grow and out grow what they have. Gets gross and no longer cute. Suddenly Person doesn't know what to do and no longer is captivated by their cuteness. Now, they're wanting to get out from underneath them because... well, they still know nothing about ducks! They might of asked a question or two about them, and all they got for an answer is "Ducks are easy to raise."
It's very sad to see, but you should hand them some understanding. I've seen a lot of birds around, and the scene I just listed off is very common. The last story I heard was some guy went around and bought around 500 (more or less) chicks and suddenly had knee problems and couldn't take care of them anymore. Maybe something you can do whenever you see something like this is to kindly help them. Politely let them know that they need water to put their whole heads in and better bedding. Let them know that they need a bigger space. Let them know that they need a pool or something. If possible, offer to help them set up a better setup for them. Then, offer to help them find a good home.
Please don't judge these people! It can happen to anybody and has happened even more than ever thanks to the panic of 2020!
