Just for the spring and summer (veggie and flower garden) growing season, you might consider trimming their wing tips so that they cannot fly so high. I know that if we want our organic veggies this year for ourselves and them, there may have to be some extra supervision until Fall after the majority of the harvest. The beautiful Summer weather here in Mt. Hood region of Oregon means our best shot at outdoor gardening until it gets dark at 10:00 pm, so it should not be too difficult to keep tabs on them. This will be our first Spring and Summer with our "free rangers" also. They were too small last year and were kept in an enclosed 1/4 acre area. We let them began to roam in early Fall so there was no noticeable problem with them consuming the garden. However, even as we began to prepare this year for Spring planting, they follow us around and scratch up everything at ground level right behind us. We will fence the vegetable planter boxes also. Good Luck, and keep us posted if you think of anything else that helps as the season progresses.
