Hi again,
Thanks for both the welcome and all of your posts. Although I just joined, I've been to the Backyard Chickens Forum lots of times in the past and have learned lots even though I grew up with chickens. I learned about the Pullet Shut automatic door opener on the forum and installed one. That door has SO cut down my worries. It also cut down my prayer life because I was spending so much time praying that those chickens would stay safe until I got home from work on my late nights!
My first rooster after moving into this country sub-division was also a dog rescue. I was down the street at my sister's house and heard our young teens out in the yard screaming and dogs barking. My sister and I ran outside to see one of the dogs with a chicken in his mouth. I managed to extricate the little fellow, but I didn't think he could possible live from probably internal injuries. He did live. And I'll swear to this day he understood I'd saved his life. He'd follow me like a puppy, even into the house. Although our community rules state no farm animals, we have a no-leash law. (Quite a few of us now break that rule and keep backyard chickens.) Even though my builder lived next door, I kept the little Old English game rooster and found him a couple of wives. For the rest of his life though, I remained his #1 lady and the love was mutual.
It's a horrible thought to think of people just dumping any animal, helpless chickens especially. I have one house that I will return to tomorrow and leave a note. One neighbor said the man there has had chickens, and I found part of "Lucky's" tail feathers at his front door. Based on the length of the tail feathers I found, I'd pretty well ruled out Cubalyas.
