I've an acre completely fenced in. Central Tennessee, Cumberland Plateau. Outside my yard I am surrounded by a farmers hayfield. Its nice and private but the hay allows predators to make concealed approaches to my yard. My birds live in a 1/4 section, my GSD Dog runs the other 3/4 acre and barks at everything--today her barking a long time at one spot of the fence brought me to see her flush out a limping old coyote who had layed up in the hay about 3 feet outside the fence. he limped off, but a few hours later I saw movement in the hay and saw him creeping in, about 50 yards off, eyeing my hens, and I took a shot him with my Henry 17 HMR -but overshot!. I've put my GSD out in the yard and she is barking her head off. and it is midnight. Hope the coyotes can not tag team her, so far I have just seen the one--an ugly old thing with a huge head and ears just like my GSDs. My hen house is not secure, if the coyote gets in he can get the birds--I've 17 hens and 1 roo. I go out every hour and do a perimeter check and have seen nothing. I do hear a lot of dogs barking and a lot of coyotes yipping in the distance. I want to go hunting in the morning and bag me some coyotes, but they are on a farmers land whom hasn't returned my phone message. I gotta get some sleep now, Rosie the GSD 4 years old, 80 lbs, strong as a bull, its up to her to warn me if there is a breech of our perimeter, I will sleep in my clothes and get up quickly if the is a problem. I now hate coyotes!
