We have 6-week-old chickens and 8-week-old African geese. The pullets are in a small run. We plan to let them range in our several-acre yard when older, as the geese do. This evening, we let one of the larger pullets out in the yard as a test, and the geese went after her pretty aggressively. Normal behavior? I hope not, because it kind of messes up our plans. Thanks for any insight.
