With ours, our geese free range so will often go where we are keeping sheep & we also keep ours at times including our rams in the field the poultry are in & generally the geese don't bother, unless the sheep get too close & we see them eating stuff together like corns - But I have seen the gander peck, chase & even hang on to tups & calfs tails with the tup or calf running with him still hanging on, & he will randomly peck hard on a tups head until it moves or tries to headbutt him as their pretty docile & the tups will often walk up to you for a stroke or head scratch - more so when the girls are around
& when we had our spaniel she deliberately teased the geese & got chased by them, but our dogs at the moment have more sense
