Hello, As the mother of three lovely ducks in suburbia it has become neccessary to build a better system to graze our girls. At the moment we have a fully enclosed pen at the back of the yard with a duck house within. Shown on my profile pic.the grass is long gone though, thus the need to rotate the yard. I need to upgrade to some sort of enclosed fencing system that I can move around easily, over the garden beds as well. I'm thinking timber frames with wire that I can bolt or even cable tie together to create a flexible pen system? For the roof I have been using bird netting to prevent sea eagles in the area having any chance for attack. If anyone has done similar or could direct me to some resources please Would love to use recycled materials and for it to be simple, I'm not the best at building...yet Thank you!
