Do chickens have to be locked in their coop at night?

[User395221]

Do cats bother chickens (I would think they would)?

I'd say that it depends on the cats..... Feral cats, for sure. A hungry feral cat, absolutely. A cat with a strong prey drive, perhaps. I have 3 cats (2 of whom go outside, one doesn't). They don't seem to take any notice of any of my birds, chooks included. But they are individuals, I wouldn't extrapolate their disinterest to be representative of cats in general. My guess would be that a well-fed domestic cat couldn't be bothered chasing the chooks, but again, it depends on the individual cat.
