Lots of hand-wringing on this one, and I can well see why.
On the other hand ....
Commercial hatcheries are businesses. They work within a regulatory framework, and economic necessity.
If you feel they are unnecessarily cruel, then it's your burden to make animal welfare a priority in a nation that still permits the declawing of cats. I wish you luck.
From an economic standpoint ..... It is a priority of hatcheries to ensure the stock arrives at the growers healthy and undamaged. I imagine the viewing of the process is worse than the actuality.
Even were this not the case, and I am sure there will be those who argue it inherently cruel, then who is going to pay the extra $$$ KFC will charge were all the chicks (tens of millions) to be handled one by one, in a manner that would satisfy enthusiasts.
Chicken is business, big business, and it is controlled by companies whose priority is money, not animal welfare. However, everytime the word *regulation* is mentioned, someone bangs on about freedom and liberty.
You can't have it both ways.
just my 2c
ps .... There are animal welfare concerns, and I share them. This is probably not the worst example tho ... I have seen much more distressing video.
