I'm wanting to move my 12 chickens from their current homes to a chicken tractor surrounded by poultry netting on the farm. the whole corner farm is surrounded by high metal fencing. critters won't be able to get in. but I want the chickens to be able to wander around in a bigger space, eat fresh grasses and move them to new spots every .... (what? month? few months? weeks?)... but my question is - what fencing can i use to keep my chickens in... and something that is also very easily moved to another location as i move the chicken tractor. help! want to do this asap!
