Quote: This is 100% true. I've been one of the lucky ones. I do have lots of cover for the birds, plus several roosters in different pens who have different vantage points when other groups are free ranging. I've seen a fox eying my flock just outside the livestock fence perimeter while two cockerels stood their ground and an older rooster was getting hens to safety, seen hawks try to dive on my birds, had a fox's den about 250 ft from the main coop, never once lost a bird to a predator in going on 10 years we've raised our own birds, all the while free ranging on an almost daily basis one group or another. I'm pushing my odds at this point and do expect a predator loss eventually.
We are home most of the time and no birds free range while we are off the property, but still, no pen or coop breaches. I live on a wooded mountain property, but when I lived in the suburbs, I saw more coyotes there than I have since living here. Folks tend to believe that being in the city, they won't have the predator losses that we do in the country, but that is simply not true. The #1 predator of your chickens, IMO, is the roaming domestic dog, but the wild predators are all around you, whether you've seen them or not.
