I am debating between trying a wormer (I have Wazine and Panacur) or an antibiotic (Duramycin-10) as a last ditch effort to save the pullet. I think she should be culled, but my family has vetoed me. They are on their second day of Corid, although I don't think it is cocci. Some background - I have been steadily losing pullets at a rate of around 1 every two weeks. I have treated with Corid, wormed several times. The pullets are fine one day, unable to walk the next, dead within two days after that. Started with 9 three-month olds, I am down to six. Four appearing healthy, one walking dead roo, and the dying pullet. The roo got sick about a month ago. Primary symptom is gaping. He also lost a lot of weight. I treated the flock for blackhead. I also treated him with Oxine steam. Neither 'helped' - still the same symptoms but he is still alive. He wasn't eating on his own for a while - we fed him moistened crumbles for a week, and now he is eating on his own. The reason I am thinking about antibiotics is that the roo is deaf. Maybe there is some sort of infection going on? Does gape worm cause deafness? I have nothing to lose with this pullet - pretty sure she is not going to make it. Her weight is far better than the roos, but she can't even hold her head up. I would love some advice - can I do both worming and antibiotics at the same time? Corid? I don't love the idea of blind antibiotics, given the problems we are facing with drug resistance from over-prescribing, but I am leaning towards the antibiotics given that nothing else has made things better. What should I do? Or, what would you do?
