Hello everyone, I recently got lucky and got land with an established flock of hens numbering around 40. However their current pen is non movable and completely bare, but I have the room to move them around to other areas. I cant move the coop, unfortunately. I was hoping someone on here had a relatively cheap method/plan to make a movable/portable run that I can let my girls into during the day and get them back to the coop before dusk. Thank you in advance!
