I recently bought some American Buff geese and the best place I have to build a permanent home is under a large cedar tree. The tree is about 12 inches in diameter in the trunk with overhanging branches, and is about 20 plus feet tall. My questions are, will the geese hurt the tree? or will the tree hurt the geese if they ingest any bark or needles? I think the geese won't have a problem, but not to sure about the tree. Any info or opinions would be appreciated.
