I don’t understand it either. It sounds like leaving the land fallow every seven years as advocated in the Bible, only for animals.That's a very interesting question. I don't know whether resistance is genetic or acquired. I would have thought acquired, but I really don't know. In any case, I'm not in a good place for roosters. He would have to wear one of those no crow collars and that doesn't seem fair to me. Also, my next door neighbours work shifts so, even crowing muted by a no crow collar might be too much for them. Certainly one of the resistant hens (Mary maybe) could go and visit a rooster, but she would become very stressed from leaving her home and from meeting a rooster.
I also don't really understand what Mark was saying about growing a crop to reduce the bacteria in the run. But it makes sense that turning the top layer deep under and bringing fresh soil up would be healthier for new hens.
One thing Mark said that might be interesting is that we could test for exactly which bacteria, but in any case, it was going to be one of the big three E Coli, Salmonella, or one other that I don't recall with confidence, maybe he said Staphylococcus. And the antibiotics we've been using are the right ones for those three, although creepingly ineffective. I've been given a large amount of powdered clavulox with instructions for mixing and dosing for Janet, with no conversation about it. I think that's a silent hint for me to try a big dose on Janet. I'm mulling that over.
I genuinely do think waiting for this flock to gradually die out, then correcting the environment the best I can, then hatching fresh chicks who won't carry harmful bacteria might be the best path for a reset. It'll still take years and years for my hen friends to die out (I hope).
In time those fresh chicks will be hens who can hatch out other eggs.
And I told Mark I would support the current hens the best I could, and that includes proper treatments when they get sick or injured, and continuing the special diet for those with dodgy livers.
But once they're gone, it'll be time to rejuvenate the environment the best I can and start with healthy chicks. Then hope for the best.
Sorry for writing so much about it and being inattentive to other people's problems. This bacterial problem is taking up my chicken thoughts.
@BY Bob I think I've worked out how to flush bleach through the misting system, but I may just take it down and throw it out.
Strange.
Some plants have anti microbial activity but I never heard of sunflowers being that way.
