Right now our chickens are free range during the day. I love having them moving around the land as they see best, but they dig in everything that I'm planting.
My current solution is to put a wire ring around every single new tree and bush (which actually helps a bit with mulching) but in the long term we definitely need another solution. We've tried the usual chicken fencing but in the spring the ducklings try to get through the mesh and get caught.
I'll keep you posted on the willow fence! First step is to grow enough willow to have the cuttings, so it's a multi-year project.
