Does anyone know how to tell the sex of this crow?

I am befriending a crow.
I like to garden and it liked to eat my worms and ladybug.
I don’t like it eating my worms and ladybugs so we are negotiating.
Does anyone know how to tell the sex of a crow?
I have noticed that it is like a bouncer, it keeps other crows and magpies away from the property and more importantly out of my garden 🪴 ❤️.
