Part of the reason why it kills so many commercial birds is because there is very little genetic variation, plus the close proximity factor.
This means that if one of a commercial flock gets it, all it's brothers and cousins are potentially also not resistant, add to that the fact that those cousins etc. are all in the same shed and you have mass death.
Why on earth they always kill off all the survivors I have no idea. It seems utter lunacy to kill them off, instead of breeding from them.
Anyone know if the flock that got it had been let out at all?
It's a sticky situation, on the one hand keeping them in and keeping wild birds out, reduces the chances of catching it in the first place, but if any do get it, then keeping them in will make them all be exposed to high levels of the virus.
Stopping people moving their birds around (off premises) and getting them to keep shoes and clothes specially for tending to their own stock is good common sense, but making even domestic keepers keep their birds shut in in an attempt to stop it spreading is BS. |

I don't care whether anyone else keeps their chickens in or not.
As long as they don't come onto my property.
If someone in this part of the country has his (or her, for the pedants) flock decimated by AI, I would be concerned, but only because it would suggest that the wild birds in my area were carrying a virulent strain.
There was a neighbour's hen that was often seen wandering free, that might potentially have been able to spread it to my flock, but some random guy's flock anywhere else is never going to be threat to my birds.
I entirely agree with NMG. I remember years ago, legislation was brought in after a nasty outbreak of F&M that would restrict the movement of cattle in any future outbreak, but because sheep often need to be moved to new grazing, NO movement restrictions would be applied to sheep. Daft muppets didn't think about stopping sales/purchases or even distance limits. So when it next got into the UK, sure enough, it was sheep sales that spread it across the country. |
