It would probably speed up recovery to have her on Tylosin or some antibiotic soon. Doxycycline, oxytetracycline, enrofloxacin, and dDenagard/TiaGard are also used for MG. Scrambled egg and her usual chicken feed are best for her. I hope that she recovers. MG is a chronic disease, and she will remain a carrier, and assume the flock is as well. You may see an outbreak in some during times of stress, such as during molting or extreme weather.
