It won't be until there is little or no chance of more transmission. There won't be a roadmap, like our lockdown, it will just end.
The previous one lasted from December 2016 until May 2017. So they could have to wait until May.
However, given that APHA have issued very few alerts in last week or so, we may get lucky and it could be mid-march. But until APHA say so, its just a guess.
Whilst I have alot of hens, and its not the best for them being locked up, I'm just glad that farmed geese are exempt. I can't imagine having to keep them all inside, clean and tidy.
