You could cobble one together out of scrap wood, it doesn't need to be an actual ladder. But yes the run is a little barren of stuff to do. A couple smaller obstacles/clutter might help break up the space and give the lower ranked birds a bit of relief.It has been on my mind to put a rustic ladder leaned up against the coop as a perch in the run, I just have to find one...
Hormones.The thing I just can't understand is they were literally all winter (when they spent most of the time in the coop) and no bullying. Now when its nice and the snow is gone is when the issues start?
