we forgot to close the door to the coop 1 night and somthing killed 6 of our chickens. All the ducks got away. Ever since then the ducks will walk 50 yards from the coop every night and sleep in a small stream on our property, they come back every morning and hang out right around the coop and our house but will no longer sleep in it. Do I catch them and lock them up for a couple weeks, so they know it’s safe?
