I have a small flock of hens, who live in an 8'X10' henhouse with an attached 10'X12' run. For the first few months, I let them out of the run to "free range." Then I lost one to a fox. I live in northwestern Connecticut, in Litchfield County. Our property is surrounded by woods and I notice many hawks, foxes, and at night raccoons and coyotes. I was greatly disturbed by the loss of the chicken, but hate to keep them enclosed 100 percent of the time. Thoughts?
