This is a longish-term project: I'd like to hedge part of a field as a
hen-run, which means the hedge needs to be dense from the ground up and 6
feet tall. I thought of privet, because I believe it's quite
fast-growing, but it would be nice to have a mixture. Suggestions
gratefully received.

My brother built a willow 'fedge' dunno whether willow is poisonous.Quick
google shows as follows. Not cheap cheep.
