I'm so sorry for the loss of your pets. I know how your wife feels. My chickens are my babies and it's hard to take such a loss. We too have neighbors that refused to take responsibility for their 2 dogs.They were constantly loose,even after 1 of them got hit by a car and had to have $15,000 worth of surgery on a broken back.(we were actually the ones to help the dog get medical attention as the owners were not home at the time) One is a bull mastiff, and the other is a st. bernard. We are animal lovers, and could never bring ourselves to harm the dogs,but there ARE measures one can take. These dogs had been let out when we had people over for back yard parties,when our grandchildren were in the yard,ect. There were times when my husband would go to put the garbage out at 6 am and the dog would be waiting right outside our garage and growl at him! We asked nicely, repeated times, for them to please tie the dogs up. We did not want to have to call the dog officer,but it continued, and the bull mastiff tried to attack my 6 year old grandson.Thank goodness it was cold weather, and his thick winter coat took the brunt of it.(although now he's terrified of all dogs) We called the dog officer and filed a complaint.They said the most important thing to do was keep a record. Call every time the dogs were on our property, and the more times we called, the higher the fine got.Not to mention we had documentation if we ever had to go to court. One day last summer,I heard my girls(hens) making a ruckus outside,and when I looked,there was the st. bernard, IN my coop, where I had babies in cages in the fron part of the coop.I chased the dog away,and the babies were scared, but ok. The next morning, one of my favorite pulletts was found dead in the coop. I believe she was actually scared to death by the dog. Nothing will bring her back. We ended up calling the dog officer about 5 times before they actually "got it" but now, those dogs are NEVER out loose,and my grandchildren & chickens are safe. I can't help you with prices on your chickens, but if I were you, before you get any more, I would keep an eye on your property, and call the dog officer any time you see those dogs on your property. The fines will get higher & higher for the owner, until he realizes it would cost less to buy himself a fence. And agree with you, it's not YOUR responsibility to fence your property. It's HIS responsibility to control his pets & keep them on his own property! Good luck and condolences. Nancy p.s. boy THAT was a long post huh?! lol
