Hi all, a couple quick questions for you experts How are off the wall does the roost need to be? is 6-8 inches enough? I wanted it close to one wall so that it would be away from the feeder/waterer to help keep those clean. Also, when chickens are full grown, about how far off the ground to I want the bottom of the feeder and waterer? Here's what I've got so far...getting there! tons of work!
