We have 10 chickens with an inner hutch and run protected by electric wire, and access to an outdoor fenced run in the daytime. We live in 'animal kingdom' and there are bears, coyotes, bobcats and the occasional cougar! Fortunately we also have 2 labs who are always on the alert . The chickens are all heritage mixed breeds - including three that lay green eggs. Last year I got 4 new Cornish black hens so they are the youngest - only 1 year now, all good layers, Stephanie
