Resting peaceful mobs to make the world feel alive

I was thinking peaceful mobs could have a little “rest” mechanic to make the world feel more alive. Like at night or when they’re not moving much, chickens could sit down, cows could lie or chew slowly, sheep could just graze quietly instead of wandering nonstop. They wouldn’t move around all the time, they’d have little calm moments where they just exist in the world.

It wouldn’t change gameplay or survival balance at all, it’s just a small tweak that would make forests, plains, and other areas feel more natural and peaceful. Imagine walking past a field at night and seeing animals resting instead of constantly roaming it’d make the world feel more real.
