Does anyone know how to encourage chickens to roost? Every night my chickens sleep clinging on to the rim of their nesting area. They make it filthy! There are roosts in the coop but they refuse to use them. They used to roost until the nesting boxes were added to the coop. The boxes are getting run down now from all the weight of the hens so I was thinking I should remove and replace them. There is another nesting place which they do lay in but the other one they sleep in. Any suggestions? The hygiene of the coop continues to deteriorate while those silly chickens keep doing this!
