One essential feature for your chicken setup is a predator-proof fence. It should go at least a foot underground and a foot outward in an "L" shape to stop any digging animals. Predators will absolutely try to tunnel under for a quick snack.

Ventilation in the coop is another must. It helps remove ammonia buildup from the chickens’ waste — keeping the air healthier for your flock.

If you're in a colder climate, consider getting a water heater. It's not strictly necessary, but it can make winter care a lot easier.

And while not exactly critical... turns out chickens enjoy Afrobeat music at night. It keeps them calm, and rumor has it, it even boosts egg production. Just don’t play rap — apparently it stresses them out so much, the eggs come out square. (Okay, maybe not really... but I do enjoy Afrobeat myself. No eggs from me yet though — probably because I’m not a chicken.)

Good luck with your chickens!
