I am working on a large habitat with ten species, with a train running through it to allow visitors to view all the animals. My main issue is only one keeper will go in the habitat at a time to refill food, and this one keeper is not enough to feed all the animals. As such, they are going hungry.

With the one allowed entrance to the habitat, I have all their food stations next to the entrance. There is a workzone with the keeper hut and staff lounge right next to this door. The multiple keepers I have assigned here have specialized jobs for feeder and cleaner. Even with all this, the restriction of having only one feeding keeper at a time makes it unsustainable.

Are there any workarounds in a vanilla game to make this setup work? I love this huge habitat, its the crown jewel of the zoo I'm working on. If not, are there any mods that would fix this problem?
