Hello....Train, and train some more ...I have 5 Dogs...LGD , Golden retriever / Aussie and a Yorkie trained to herd Birds..Have a key word like OFF that your Dogs respond to instantly...Until it's responding never trust it...Have all basic commands in place and sit with the Puppy on a long lead as the Birds free range around you..Correct the pup as needed and praise when the pup gets the lesson right..
Best wishes!
