I have a Black Australorp that started sleeping in the nesting boxes. The nesting boxes are filthy and whoever is laying eggs is leaving them on the coop floor. She's about 6 - 7 years old (yeah, I know....I'm going to start keeping a notebook). I assume it's because she can't jump up to the roost or more likely it hurts to jump down (I saw her slightly limping for a few days). The main roost is probably 24 - 26 inches high. So yesterday I made a small roost that's a foot off the ground (less if you measure from the think layer of wood shavings. I took out the plastic bins I have in the nesting boxes to soak and clean. She's not going onto the new, low roost. Any suggestions? And now I'm also concerned that the other chickens might hurt themselves jumping down from the roost if they land on the base of the low roost.
