I have had a series of roosts in our brooder since their second week and all of my girls (8) love them. The first one is super low and within minutes of it being installed in the brooder three of girls were up on it. Fast forward to now, no one actually beds-down for the night on the roost - they all still prefer the warmth and comfort of their sisterly pig-pile, but they do nap on them during the day. Could it be the roost boards are too large for them?
