hi peeps the title says it all really, what widths would my new chickens love the most? shold I get a rounded perch or a flat perch? so far I have seen a 4 inch wide perch is great so they can cover their toes? I thought at the start i should get a rounded pole of sort but not really sure now. Also how far should the perch be away from a wall? i am hoping to get a poop board in too so how big should i make that too?
