I live in suburbs. Everyone has fenced properties,some are electric fences. We have lost 3 chickens in the last week. 2 were babies and might have been taken by an eagle but disappeared without a trace. The other was a fully grown hen,easter egger,nice and big and strong. I found her with her insides ripped out and feathers all over the place. Her neck looked broken but her back and wings were intact. Could this be the work of a domestic cat? Or a dog? It is likely there is a genet or mongoose type animal in the are since we do have mostly acre sized properties, but I've not seen it.
