I leave for work very early, and have been opening the pop door for the girls as I leave. These days, they're still snoozing, and don't even come out when their door opens; sunrise is about a half hour to 45 minutes away. The coop opens directly into my backyard (I'm in a suburban area, with 50'x100' lots). I know raccoons, foxes, possums, coyotes, and skunks also live in the area. My question is, are nighttime predators still skulking about just before dawn, or do you think my girls will be ok? What time do you open your coops/let your chickens out to free range?
