I think everyone at Backyard Chickens can relate to what you go through losing a battle. While with your dog or cat there's the vet ,that most of time can turn things around, you really feel alone in trying to make decisions about sick roos or hens. It seems it's always trial and error and a lot of worrying that you make the best decisions. I had people smile as though my chickens problems are amusing but only those of us that deal with these special backyard pets really understand the bond you have. My heart goes out to you because I know the loss you feel. Our roo is very sick now and we'll probably experience the same thing tomorrow. Lots of joy and lots of heartache but they're worth it. God Bless!
