Yes, having two, gives bigblueteach time to think about the future without having to act soon (apart from making it safe).I'm glad your one has a companion.
Sorry for your losses

Do keep these 2 safe. A predator often comes back.
Not where I live. We have no coyotes but the foxes often kill several chickens and take just 1. They tend to kill the whole henhouse if the chickens are locked in. It has a name too: surplus killing.Leaving the bodies and just taking one is what I associate with coyotes. All my fox experience is "grab one and go".
