I agree. My neighbours keeps geese with pigeons and chickens. Chase or catch the chickens and pigeons the geese will not be bothered, go after a goose they will panic and wht not.
Geese usually won't protect other fowls and are not the best guard animals but Chinese I think will be the best for atleast alerting you. You should get a guard dog if you can or fence your area if you can afford it. Geese cannot stop dogs. Dogs can kill goats, sheep's and even alpacas and will...
