I can't seem to figure out how to get my 5 hens (2 EEs, a Marans and two silkies) to get up or down from the roost bars in the coop. I have one about 2.5 feet high and one about 3.25 feet high. There's a board with strips of grippy stuff like a ladder that they should be able to use to get up and down, but they won't. I have to lift them up there in the evening and literally lift them back down each morning! Any ideas for how to get them to do this themselves? Their nestboxes are about 18-22 inches up off the floor and I have a little stool for them to climb up into them..So if I lower the roosts much, then they won't be higher than the nestboxes, which I understand is a must. Any ideas? Thanks!
