I think you may underestimate the scale of poultry slaughter in the US.

Also, the chicken you eat and the chicken that lays eggs aren't even the same breed at industrial scale.
Also, I know that many regulations, including USDA regulations, are a bit of a joke in the US, but bird flu is one thing they very much do not fuck around on. The loss of those 60 millions birds is a straight economic loss that's non-recoverable for those egg producers.
Now, if you had different numbers, that would be a thing worth discussing.
That, and the numbers from slaughters are chickens being slaughtered for food. Other cull counts are related to male chicks being culled in prepping for egg laying, which is also not relevant.
These are full adult flocks of active egg-layers being culled. It has SIGNIFICANT impact on egg production.
