hiya. I keep my chooks and sheeps seperate cos I like to pass the chickens a bit later, to clear up any parasite larva(takes about a week to turn into maggots)..I use a standard sheep netting( get one that kinda "stands up" on its own, a bit) on really difficult land( old vine terraces in the Ardèche, France) more than 45°slope. Works a treat!..I use a electro net, finer weave, for the chooks...I don't shut the hen house at night. Everything fine. In the area there are pinemartins, stoats , foxes, wild boar, and hunters' dogs(honestly, the biggest constraint...some folk just don't know how to train their beasts!!)..Hope this helps.
