I have set up a small run for the lone call duck inside the big run with the chickens (moving her back to her own house at night). The flock doesn't seem bothered by her, more interested in her food (which is the same fermented feed they get) and Ichabod has perched himself many times on the top of her pen, knowing full well he has access to her but doesn't go in. My daughter also brought a large nest in a tree top right above the coop to my attention yesterday afternoon. I suspect it may belong to the hawk. I don't recall it being there before and I'm not sure what I can do about it. Hawks will rebuilt old nests and I fear I'll be dealing with a very hungry clutch next spring which means zero free-ranging.
