Hens prefer dark nest boxes for egg laying. In the past we have used scraps of shade cloth to darken our hen’s nest boxes but we decided to try something new this time. Legs of old denim jeans! The shade cloth begins raveling and wears out quickly – it will be interesting to see if the denim wears any longer. We have heard of using strips of rubber from old inner tubes – but we didn’t have any available and, we’re wondering if the black rubber would hold too much heat in the nest boxes in the summer time. If you have experience using reclaimed materials for farm uses, we’d love to hear your ideas!
