It's very heart warming to see all of the positive responses from my BYC friends---thank you all. Maybe the thief will read this thread and have a change of heart.
My guess as to why that one bird was stolen is because Lavenders are still not all that numerous...and the person I "suspect" actually tried to buy Frank from me before.
The dogs must be rehomed because this is the second time they have killed and mutilated birds. I know the dogs are just being dogs.....but they can enjoy life with someone who doesn't have chickens.
A special thanks to Judy for posting the pic. Frank is such a handsome man, and his wives do miss him.....
I hadn't wanted to break the news to my husband, because he has so much on him right now, but he phoned while the sheriff was here. Of course he heard them talking in the background, so I had to tell him what happened. At least he's in agreement that the dogs must go.
Thanks to everyone who is keeping an eye open for Frank.
