Last night a possum got into the run. Fortunately I heard one of the chickens screaming (that was an awful sound--almost like a human) and ran out and scared it back up into a tree. I live in the city with houses all around so I could not shoot it. One of the girls lost some feathers but they all seem unhurt. I'm going out to check them all now. Will the possum come back during the day? My girls are locked in the coop right now but I'd like to let them out if there's no chance the possum will come back until tonight. Thanks.
