I have 3 goslings, 1 month old, in a fenced area surrounded by 16 wk old chickens who seem immensely interested in the goslings, esp the roosters. I'm concerned the chickens may be aggressive towards the goslings. How long should I wait before allowing the goslings to free range with the chickens? They are as big as my Mallards now & quite clumsy - definitely not able to defend themselves yet. I am looking to rehome all but the smallest of the roosters now (just in case someone in St Lawrence Co., NY needs a rooster). TIA
