It's been a sad day here, the King is dead, RIP King George. Never had a day of illness and death was obviously sudden.

That is just terrible news. I so feel for you, for the losses you face, for the worry you are dealing with . ..... Fancys' links contain a heap of helpful information .... found them very interesting.
I think the new task - building another run and coop is an excellent idea, as far away as possible from the current coops / runs. The following link promotes natural remedies and preventions .... also an interesting read. http://www.fresheggsdaily.com/2013/10/handling-contagious-illness-in-your.html .... if you are inclined along those paths as well.
From the link mentioned by Fancy, it would appear that replacements can ultimately be placed on 'the same farm', from clean stock. So I am presuming it does not live in dirt, leaves etc. But in cleaning thoroughly all your areas for your chickens, especially for the hens you keep - I think I would also shovel the entire top part of the run right off, get rid of it, and perhaps spread new dirt from some other way off area of your property, or purchased dirt, over the freshly exposed ground. Just to be on the safe side.
But your Vet knows much more about management of it all than I do ...
From what I have read - the only with-holding period is while medications are being administered, and I would with-hold them for a couple of weeks after the end of treatment ( which I think is usual anyway ). But then, they are not likely to be laying too much at this time.
My heart goes out to you, with this awful problem - but it can be managed. Take heart from that.
Cheers ....
I hope there are no more signs of sickness in your flock. I'm keeping my fingers crossed for you.

So very sad to hear of your loss Fancy .... A magnificent bird - from baby to adult.
How strange and very distressing, that poultry can do that - simply pass away. ...
RIP King George .... and

My granddaughter (3) says can we have one too it lookscute. Then she saw SilkieChickStars and said can we have them too! I really don't need another enabler.
But they are beautiful. Hopefully we will have 6 more babies by the weekend.
And my Mabel is just adorable, and so soft. She's really getting into cuddle time before bed. You may need to get an Araucana after all 
Just think of how exciting it'll be for the grandkids to collect those pretty blue eggs! Yeah, I'm a pretty bad enabler, hehe.
Ohh six little ones sounds wonderful! Make sure to post pics
Though on a practical note construction on the new coop which had stalled for a while, is now powering ahead. It's going to be big, secure, and built with the seemingly endless Queensland summer in mind. I'll try to post pics tomorrow. Getting the posts put in and the frame to support the roof of the run constructed at the moment. We were also busy clearing away tree branches and garden debris today, Ada and Annabelle were keen to help of course, should anything edible surface.
