I,m going to start on building the roost soon for 50 birds . I heard not to build a pyramid type because they could fight over the top roost. I have enough room to put 2 -25 foot long 2x4 's at 4 ft high is that too high ? also if I'm using a 2x4 for a roost with them sitting on the 4 inch side how wide should the poop board be underneath them ? i,m assuming it needs to be centered because they can poop off either side .
