Many of you will remember my fiasco that I went through this last summer with my flock being infected with Infectious Coryza. I treated my flock with Gallimycin after consulting two poultry specialists. I recently had a fellow BYC'er (Wynette) PM me about the use of Gallimycin in egg laying hens. She was told that if Gallimycin is used in egg laying hens, then you could never eat the eggs from that hen again. This is NOT true. I have contacted Dr. Pierson again (he's one of the vets that helped me through the Coryza) to get his advice on this matter. This was his response: Gallimycin is actually one of the few approved antibiotics for egg laying hens. It is even used in commercial layers through their feed in times of illness. I recommend that you give the hens a full clutch cycle to rid themselves of the antibiotic plus a few days after you discontinue the Gallimycin. So you would wait 12 days and then the eggs will be fine to eat. I also would like to elaborate on who this vet is, for those of you who are wondering about his credentials. He is the head vet in the poultry science dept. at Virginia Tech, which is a veterinarian school. He teaches as well as handles poultry cases from all over the state of VA. He is up to date on all of the newest procedures and information, so if he's says it's fine to use Gallimycin in laying hens, then it must be! Just FYI!
