I am pretty sure thier is a seasonal pattern to hawks targeting my birds. Starting late September and ending roughly November I have increased presence of juvenile Coopers hawks that appear to be flying south. For me they seem only to go after juvenile chickens and a rooster seems to put a stop to losses, as does dog. During winter months when most of flock is confined I have had red-tailed and even a Feruginous hawk, latter normally has a more westerly range, go after free-ranging red jungle fowl hybrids and American dominique hens. Deep snow for several days usually before hawks visit. Hawks involved appear to be local at least that time of year and may actually be targeting rodents with chickens being targets of opportunity. Heavy cover greatly helps reduce such losses and dog stops them. Spring migration appears to involve fewer Coopers and vulnerable birds (chicks and juveniles) effectively protected by adults (and now dog). Sharp-shinned and re-shouldered hawks not threats.
