When I had my coop in a different location, my chickens would go out the door and make a bee-line for a spot where they would be in the shade,able to roost,and to eat bugs,ect... I moved the coop so the windows will face south in winter and so I won't have to move it later( it was supposed to be a tractor but it got too heavy). It is only about 20 feet from the original spot. Now only a couple of them go out. I can't even coax them out with bread, their favorite treat. Any ideas what's going on?
