I'm getting ready to build the roost inside my coop and have a few questions. Thanks for any info you can give me! 1. Should all the roost be the same height and if so do you build a ramp for the chickens to get to them or do you build a ladder type roost? 2. How much space do you allow per bird on the roost? 3. If making the roost out of 2X4's, do you lay them flat or turn them on edge? 4. What should the height be of the roost? 5. If you do build a ladder type roost, how far do you space them apart (both height and width)?
