Ive had 3 chickens for about 6 months and they all used to go inside the coop at night to roost. Lately most nights 1-3 of them will be on a fence post instead of in the coop. Some nights all 3 of them will go into the coop, some nights all of them will be on the funce post or some comnbination thereof. How do I get all of them going into the coop everynight. Ive read everywhere that they always go to the same spot to roost but mine seem to go randomly to the coop or fence post. Any ideas?
