I have four hens that are 1.5 years old and they have always slept in a pile in the corner. I have eight 4 month old pullets that always sleep on the roost that I added a couple months ago. Do you think I could get the older girls to roost if I continue to place them up there night after night or are their habits be so ingrained at this age that they are unlikely to accept the roost? It certainly does make the clean up easier with the roost and dropping board set up. If ayone has had luck getting mature hens to roost, I would love to hear how you did it. Thanks!!!
