This evening just before dusk my wife alerted me to a commotion in the backyard. She said a very large dog was chasing one of my dominque roosters. I ran out and saw a rather large pit bull pushing 90 pounds galloping around yard with a teen age kid and his father in pursuit. Where the dog had already been two dom pullets were laying injured on ground. Dog owner promptly offered to pay for losses, I suggested $4 for each pullet to be generous. Dog was half heartedly going after another bird when I yelled contain that dog. The kid gave me rude confrontational response before his father intervened and told kid to get dog. The dog then proceeded to neighbors coop and pond where it flushed geese and tried to get into a well built coop of 20 x 40 scaring the crap out of the chickens and peacocks inside. Folks pursuing dog increased to five as they converged around neighbors property. I promptly began assessing losses I could find, two birds down with one moribund and other busted up, possibly with lung / air sac damage. Several birds could not be directly found because they either hid in heavy vegetation or flew (red jungle fowl and games) to up to safety on either roof house or trees a couple hundred feet away and 30 feet up. As I began policing damaged birds the dog returned and chased other birds on ground strait to me. Doms cannot fly well enough to save life from opossum so they were in trouble. I stepped between dog and yelling and growling to get his attention. He stopped dead in tracks about 10 feet from me and looked at birds struggling in my hands and approached. I crouched down getting ready for a wrestling match and the SOB stared at me not the birds and gave a growl. He appeared to be sizing me up. I figured backing down was not an option so I gave my best ticked off crazy bull ape imitation (for me comes natural) and bluffed him out. I am three times the dogs size but he would certainly get a few good bites before I got him down. I yelled very loudly in direction of trailer court that dog was back threatening my chickens and if he was not contained he was mine to do with as I please. The owners came back giving chase again with dog going back to neighbors poultry yet again. Thereafter dog and pursuers were off to parts unknown. I then started looking for birds coming back from their refuges. My trained rooster Eduardo was one of those flying into tree across field. He can fly! Apparently owners had little or control over dog and appeared to me they were a bit scared of him. Found out later same dog bit neighbor kid in chest and he showed me the scar. This dog is going down the road of SSS and pursuit will go to owners door step if need be. As I composed this dog came back a yet again but left before owner of geese arrived with rifle. Luckily this occurred on a Sunday when I could intervene and the dog was a relatively incompetent chicken killer.
