Thank you all for your advice about where to find pullets after my flock was killed.
I found two 9 week old pullets from a nice lady in a local Facebook group. She only charged $10 each which I think is a low price considering that day old chicks are about $5 at my local feed store. And I know these are hens for sure because of their age so it's worth the few extra dollars to me for the peace of mind. I would love to have a rooster but am not able to where I live. I think that's a dumb law since a lot of dogs bark at all hours, but anyway...
The pullets are healthy and are doing well. My last survivor is making a good recovery. She still has a large wound in her back from the dog attack, but it is healing and has remained uninfected.
I built a new run with 6' tall dog kennel panels, a wire apron around the outside and cinder blocks on top of the wire apron. It isn't pretty but was the cheapest, quickest option. I have thicker hawk netting over top the whole enclosure. It's not raccoon proof but I am hoping it is dog proof.
We found out whose dog killed the chickens. It was a husky from a house almost a mile away which explains why I didn't recognize it as a neighbor's dog. This house has three huskies apparently. The husky got out of its yard, came back to our yard and went straight to the (now) empty chicken coop last Friday afternoon. The other two huskies were found running along the freeway overpass a few blocks away from our yard. I found out the owners name and where they live but am not sure how to approach them about this because you never know how people will react. I want to say something because the police told me this person's dogs get out a lot and they don't seem to be super concerned about it since it keeps happening. The police told me husband to shoot the dog if we see it in our yard again if our animals are out there. Yikes! It makes me worried it will happen again. I've made some changes since this happened but I feel like I'm kind of a sitting duck now.
From now on, when I am not home, I lock the girls in the small, more secure run. At night, they are locked in the coop which is predator & racoon proof. Racoons are not an issue for me but I found out why when I was talking to my neighbor after my flock was killed. My neighbor has been trapping them for over a year since I got my chickens! I had no idea! This has been really hard but I hope it gets better now. And I hope I can think of how to approach the dog owner. Personally, if someone thought my dog did this, I would want to know. But you never know how people will react...
Have a good Saturday!
