First, THANK YOU for not getting an LGD for chickens. Not only your neighbors, but likely you as well will be much happier for that decision. They don't actually bond with poultry, they only guard them peripherally, when they aren't taking them out themselves.
Now, what you can do - 2 acres is not that much land. Put electric fence around the whole thing. I don't even bat an eye at putting electric fence around 2 acres at this point
Specifically to rotate your birds, Premier 1 has electric poultry netting.

About dogs - do you already have a dog? If so, any sporting goods/hunting supply store sells bottles of scent. Get the raccoon one and train your dog to bark at that smell. Even if you have a chihuahua, if it will tell you where a coon is, you can then take care of it.
If you don't have a dog, get the bottle of wolf urine (yes, that's a real thing). "Mark" your territory. This keeps a LOT of predators away - see, predators don't let other predators in their territory. Wolves will actively hunt and kill fox and coyote, who instinctively know this. If you are a fellow (or, if you're a lady, it's just a bit harder) you can mark all on your own, too. It really does help keep away everything but feral dogs.
If you want a dog, any herding breed I've ever had will protect my birds because they are mine, and they take care of what's mine. But keep in mind, every pup needs taught. I've lost one (and only one, but still one) bird to every pup I've ever raised. Dogs take time and training, but raised well, nearly all of them will protect birds - the rare dog because it likes them, the owner-attuned dog because they're yours, and most any dog because ... predators don't let other predators in their territory.
I buy copies of this book to give to anyone who gets a dog from me (I foster)
