How do you get you chickens to use a roosting bar at night? Most of mine choose to crowd into the corner where their nesting boxes are, all into 2 boxes knocking each other into the floor instead of the 3 12 foot bars set up for them. I take them and place them on the bars but they head back to the boxes. Should I block off the boxes to train them? They're only 3 and a half months old so not yet laying so I don't know if it's an issue or I assume they should be trained now. The bars are 2x4s and higher than the nesting boxes.
