I was convinced my hen, Red, had canker, but she did not respond yet to Metranodazole, and now is starting to bleed in her mouth. SYMPTOMS - starting drooling clear mucusy liquid one week ago - has big gooey clump of "cheese" in back of throat - at first had horrible breath, but no longer - struggles to eat or drink. Gurgles with head up - has clear nose & eyes - no coughing or sneezing - walks around quite a bit (she is free range), but otherwise slumped by herself - is VERY thin - is old (5+ years) - rest of flock (17 girls, various ages) looks pretty good TREATMENT SO FAR - The first day I swabbed her throat with VetRx and some cheese came out and a little blood. I also massaged her crop. - After some research, I ordered some Metranodazole to treat canker. - In the meantime I daily swabbed her head & nose with Vet Rx, fed yogurt or eggs with garlic and gave some Gatorade. - last 4 days she got the Metra, about 100 mg/day - tonight she was drooling out some blood and I gave her some Metcam for pain QUESTIONS -The vet suggested LS50, as an upper respiratory antibiotic, but she doesn't seem to have those symptoms? Should I try it anyway for the whole flock? - I'm also worried about things like wet pox, coryza, etc, but she doesn't seem to have quite the right symptoms? - Was my dose too low for Metra? I'd did not seem to improve at all, so now I'm thinking it isn't canker. The other girls are doing very well, but I'm worried that they got some germs. I just separated Red tonight when I saw the blood. Tomorrow is Sunday, but Monday I will probably take her to the local lab for euthanasia and diagnosis. I would have sooner, but it's a 2-hr round trip drive, and also I guess I wanted to give her a chance. Sorry this is so long!! Any help, input etc is welcome! Thanks!
