I've read here that others have had problems with their chickens not wanting to roost. I want to know what causes this behavior. Any theories? Do I have insecure chickens, or what? My chickens are 13 weeks old and they are not using the roosts. It's very frustrating because they are using the nest boxes. They roost on the raised lip of the box which can't be comfortable. They are even getting good at balancing on the slanted tops of the nest boxes. I plan on stapling cardboard over the front of the nest to keep them out. They need to be power washed and sanitized before egg laying. The roost are about 4 foot high but there is a ledge at 3 foot and a ladder to help them up. I don't remember my other chickens taking so long to roost. So tell me, what is lacking in their chicken life that they won't roost??
