I know what a crushed egg looks like, but how are they sold? Maybe someone can clarify for me what are crushed eggs used for..? How does having a crushed egg help with anything?

I googled it, and still didn't come up with anything.

and having the shooters kids kick the wounded birds until they (the birds) are dead?

I can see the restricted hog farms - some of those farms are environmental monsters with the waste dumped into waterways.

Trump's pal, Ted Nugent, is somehow involved with this?

Really? They take a couple of comments from a PETA member and use it for fear-mongering.

The restrictions on "hog farming" were attempts to control factory farms and the cruel way that sows are confined to produce piglets. The Missouri thing I believe was about attempts to stop rampant puppy mills. I'm sure the others are just as bogus and conflated.
If anyone thinks it is the farmers who are threatened and not those who would stand up for humane treatment of animals, just find a copy of the book "Operation Bite Back".

https://en.wikipedia.org/wiki/California_Proposition_2_(2008)

This law (a citizen initiative that passed by the highest margin in California history) required caged livestock to be put in cages that allow the animal to stand up, turn around and extend all its limbs. It turns out that a chicken needed twice as much room to be able to do all these things.

I found this: https://www.universityofcalifornia.edu/news/how-californias-chicken-industry-rapidly-changing

The good: the chickens are more comfortable now. Some of the farmers learned that chickens in bigger cages need "enhancements" like perches or they get stir-crazy.

The bad: Many very small egg producers went under. These are the guys that couldn't afford to, or didn't have the land to, double their barn space and couldn't survive on flocks half the size of their pre-Proposition 2 flocks.

The really good: Restaurants are demanding cage-free eggs now. They sell at a premium to battery eggs, so a lot of farmers are complying with Proposition 2 by removing the cages entirely from their operation...and making more money in the process.

Isn't it lovely though...two of their sources (Ingrid Newkirk and JP Goodwin) have almost no credibility among the Left, and the laws he's screaming about are really good ones.
