hello, im confused because my five chooks/roos are not sleeping on there roost anymore! They started sleeping on the roost a couple weeks ago then only some of them,and now none! all just sleeping on the timber.Does anyone Know why this might be happening?i thought it might be because its all one height or there to big for it, it is pretty squishy with 5 on. I will post a pic of the roost. thanks!
