I am setting up a “holding pen” outside the coop to deal with this problem -it’ll be a ~3x6metre deep litter area with permanent fencing- then I will run 4 or 5 electric fencing “petals” off the main coop so that my 22 chooks can graze one area at a time. Access to the paddocks will be through tidy little doors if all goes to plan, and through a bottomless 5 gallon bucket wedged under the fence if, as usual, reality gets in the way!
