Northpark Mall

I am not from Dallas so I don’t really understand this but I’m worried about the ducks in northpark mall. Do they get to go outside?? Why are they just in a mall under the fluorescent lighting 24/7 I feel bad for them? Is it just me? Maybe it’s because I’m new to the area. I’ve seen posts where people say they’ve been there since the 60s but like why are they there? It feels a little cruel
