Bird-netting placed around the tomatoes (but not resting on them) will help to prevent birds from pecking. You can attach the netting to a homemade wooden frame shaped like a cube. Squirrels can sometimes chew through the netting—in that case, construct a cage with chicken wire. Make the cage light enough, though, so that you can easily lift it (or have an access panel) when you need to tend to your plants. As for size, allow for the growth of the tomato plant — indeterminate tomatoes can grow quite large. Hope this helps!
