TLDR: 1) we still have a bird flu problem, but have smaller flocks in the farms, so the impact of having to do a cull is far far less and
2) we have supply-management for poultry and eggs and dairy (basically a form of central economic planning around a quota system) ... which in good times is a rip-off for consumers [and some farmers] but in bad times... turns out to provide some value (which is why it was rolled out in the first place)
