I love my geese (just as well, nobody else does

) You can tell the sexes quite easily, the geestapo have an upright stance early on, strutting and posing like most males. The girlgees keep a low stance with their head down ( I want to slap them and tell them"Don't be such a victim!!")
They are excellent at keeping away unwanted visitors and keeping children in check

To keep the ganders respectful, take each one gently by the neck as they come out in the morning, give it a very tender shake and look sternly at it. They will soon learn to love you!!
