I have moved perches around a couple of times and can't seem to them just right. One of the chicken always struggles to get down, but always goes for the top roost. The problem I have is that the coop is narrow (8X4). Right now they are are about 4 and 5 feet off the ground with nesting boxes under on 4 foot side. I added a lower perch with poop board along the long side which is about 3 feet off of the ground but they seem to prefer the taller perches. The long one does impede the area that they can land in from the taller perches. Most of the time they get down with very little issues, except for the one, but other times they seem to struggle. So my question is...Is there and ideal height for perches. I have large chickens, Black Sex Link, Rhode Island Red, Plymouth Rock, Wyandotte, and 2 EE. Also is 8 feet of total perch enough for 6 chickens.
