For crying out loud. I've about had it with all the bad luck lately. One dissapeared 3 weeks ago. A fox is the main suspect. One died in my hands a week ago by what looked like an impacted crop. And now we have the sister of the one who disappeared with a rattling sound in her breathing. It's seemed like an on and off thing but I guess it's time to call it chronic. In searching I found an illness called mycoplasma which sounds like a big problem. A friend who has chickens told me to try some sulfer tablets in water. I hope this works. I love my chickens too much, and have had it with the heartache, which I know is to be expected sometimes but good grief enough is enough. Anything of help in feedback, as always, is much appreciated.
