I would also recommend getting a solar fence charger and run some electric fencing around the lower perimeter. I posted some time back with photos of this. https://www.backyardchickens.com/t/928849/55-dead-chicks/10#post_14184913
It works great, First thing a predator does is come sniffing around the perimeter to check things out. Fence zap em, they go running off. The other thing you need to look at is the gauge of the hardware cloth used. I've seen some prefabs with hardware cloth a puppy could push through. I got my coop from the Urban Coop Company. The panels all come off so it's easy to put up anywhere. It's amazingly well built, well thought-out, ventilated, sturdy and I couldn't be happier with it. I've added a 4 X 8 foot covered kennel for additional run space during the day. I'll be changing that out to a 10 x 10 when I get my other birds.
