The neighbor hadn't replace the batteries in his datsun's shock collar, so today while I was out running errands the dog dug under his fence and into the chicken yard. He killed my Buff Orpington and mauled three other hens. Most injuries are on their rear ends, and they seem very traumatized. However, my cochin has a good 1" gash on her leg and you can see muscle and tendons within. What do I do for her? I took all three hens and wiped their wounds with a clean cloth and put Neosporin on them, but I am very concerned about the cochin. Help. I am a newbie to raising chickens, and I am surprised about how upset I am over my girls. I just feel awful for them, and they were once so beautiful, but now they just look terrible. I would appreciate any advice that anyone has to offer. Thank you so much!
