My silkies have been outside full time for a few weeks now. The hen house and run are designed so that they can use the nest boxes in bad weather- except they have not used them once. They don't use the roost bar either, even though they have a ramp. The house and run and covered but it's wet and windy today so I thought might use the nest boxes. Also I've left the door to the run open (on nice days) to let them have more space and roam around, but they don't want to leave the hen house. This is my first time owning chickens any insight or advice would be appreciated!
