I am in agreement with your advice and others! Can a puppy round up chooks and not be hurting them? My husband got him for our sheep but he chases our bantams and too young to tie up with our other dog yet! She is up where our ducks and goose were taken and good with our bantams and Shep but I am not sure with our puppy!Never let her off a leash when birds are out and make sure the pen is secure against her. Size of the dog does not matter. We've had toy breeds wipe out our pekin flock before and those ducks were the same size if not more.
