My goats live in a 100 x 30 pen. They have a 10x15 run in shed and a calf hutch that they can go in - yet they choose to lay on the barrels that we have stacked up for them to climb on. The weather here has been fairly mild at night and they have been sleeping on the barrels all night. When the horse gets here they will not have access to the stall at night - just the calf hutch. Why do they lay out there all night and not go into the stall or calf hutch???????
