I adopted 2 silkies hens (2 years old) yesterday and today my beagle/basset mix killed both of them. I already had 2 hens (silver laced Wyandotte and white leghorn) for a while and my dog never payed them any attention after a couple days of training him to leave them alone. He is an older dog and very calm. I thought nothing of adding a couple more girls to my flock. My husband let our dog outside (I was at work) and he returned with feathers in his mouth, my husband knew to investigate and found both of our new girls dead. I am heartbroken. They were considerably smaller and more doscile then our current girls, was that a factor? I am scared for my other hens and am only letting my dog out on a leash now. I have a fenced in backyard in the city and have throughly enjoyed letting my girls free range with no worry of their safety (at least not from my dog, I know there are other predators) should I build my girls a run? Or was this a one time thing because there were so easy to catch? I am at a loss. My dog is practically my child and I knew there was a chance chickens weren't in the cards for me having a hunting dog but he acted so well with the first two I thought we were over that fear. Please don't judge me or post hurtful comments my heart is hurting enough. I am a HUGE animal lover an do would never knowingly put an animal at danger. Thank you for any advice you can offer.
