Hi Happy, welcome. I, too, am a cat/animal lover. I have about 2 ferels running around but I leave dry food out for them and my own 3, in/outdoor cats. Less hunger, LESS DESIRE TO HUNT.
My cats don't like having the chickens come too close, which cracks me up! I've had to chase 5-9 (?) wild birds through out the cabin, hand towel to cover and calm it, in hand, because my cats, AGAIN THEY HAVE FOOD, want to play with that thing 'that moves all by itself...'
I thought hawks and owls prefer open areas; won't go under a roof for a prey. So your chickens should be okay, from them, on the porch. I know someone in the big city who still has ONE neighbor who crabs when one of the chickens gets in her yard, free eggs were declined. Wish you were closer, could cut down some saplings, give you some hog wire, hay string.....
Good luck!
