Agh!! Do you have a vet who will prescribe something for you? If you can get your hands on Baytril, it's a bacteriocidal that works better on poultry respiratory disease than most other drugs. It's got a different method of attack, and hopefully will turn her around for you quickly.
I hate to tell you this, but the eggs didn't get out- got returned to me because my label got lost. In GOOD news, I did just hatch a bunch of Silkies! Perhaps I should send you some? PM me.
