Hello everyone. I need some help! I have just finished a really nice new run and hen house. The three chickens I've moved from the old run will not go into the hen house to roost despite a lovely perch, nest boxes, warm straw. I've tried putting all the food and water in there but they will not use it prefering to roost in the freezing cold on the perch outside. In the old run they had been roosting inside since the weather started getting colder. Has anyone any ideas what I might have got wrong or any tips on getting the little devils to choose inside at night. Thanks!
