I'm not sure that 2 weeks is long eenough to get the TB to be evident -
probably it is only long enough to stress the previously latent TB into
activity and then it will take a few weeks to really crank up

Then I guess it depends how stressed they were and how long it took to
batter their way through from breeder to wholesaler and holding before
shipping out.
