This is the chief reason why Canada's egg prices have remained sane while the US has exploded. It's not like we don't have bird flu here and we haven't had culls. We just have smaller flocks.

Still, backyard chickens are a hobby, for if you like chickens. It will always cost more than an egg farm.
Then imagine spreading that misery to all the wild birds you love in your neighbourhood.
There was some move some years ago here in Ontario to push for a small flock exemption to allow for egg & pooultry sales outside the quota system for flocks under 300 bird. And I don't mean roadside sales, but market sales. So there has been some accommodation for smaller market players.
From what I understand there is no path for the small flock program to get from 300 birds to full up full time. I'm sure 300 birds/year is still hobby farm. Nobody is earning a living on that.

Presumably the risk of spread of bird flu to humans increases though, due to the increased amount of contact. And then the increased risk of mutation leading to human to human transmission.
Bit wild to me that we don't seem to be taking this very seriously other than "o no my eggs" given we just had a pandemic a few years ago.
