Brief context: I have 5 rescued Ameraucanas, we've had them since November and this is my first foray into having chickens. I thought they all loved perching in trees, etc. but mine will NOT perch outside their roost. I've tried various branches (we live in the forest), different heights, etc. and they show zero interest. We have one of those swings-- nada. I've picked them up and gently set them on the perches but they'd only put one foot on it and immediately want to run away. Are there some chickens that just don't have that "jungle fowl" instinct or am I doing something wrong? Also, do perches have to be level or would a slanted one potentially be interesting?
