There's now numbers showing that the bird flu, real as it is, did not result in a significant dip in egg production in the US. Egg producers increased prices on the news about the bird flu and kept increasing them while it was still going. Cal-Maine, the largest egg producer in the US made record profits during this period and still do. Their profit margin went from around 7% pre-pandemic to 25%.

So while disease protocols differ, that's not what drove these price hikes. Instead it's the same scheme various oligopolies have been pulling since the disruption of the pandemic. Some reasonably sounding cause for price increses circulates in the media, manufactures consent for price hikes with the public, price hikes occur, they keep going for as long as media provides cover, afterwards prices may stabilize at the higher level, people's attention moves elsewhere.
