Eggs

But, do they?
I wonder how many of those toxic chickens get sold to pet food companies and are what's called 'chicken" or "chicken by-products" on the ingredients label?

IDK, he seemed pretty serious and the FDA isn't someone to fool with on something like that.

I used to deliver boxes to several egg operations and pick up eggs at another for a WalMart DC. The egg places were some of the largest on the East Coast. I got to talking to the dock supervisor at one of them and asked who bought all of the chickens after they were done laying and he said no one. The chickens were so toxic after all the anti biotics and hormones they received to produce eggs that the FDA made them incinerate the chickens and bury the ashes.

I doubt that was anything thats happened recently. There are very strict laws regarding treatment of feed stock animals, from the FDA/ USDA and withdraw/ wait periods that must be observed after any treatments happen.

This article is dated by today's standards, but information is pertinent non the less.

all the laws/ regulations are fairly easy to look up.
Regarding egg layers, they are rarely kept past a first molt periods, seems what is done with them can vary depending on the operation. I haven't found any information that they are incinerated, rather killed then composted, or sent for meat uses, ie dog food etc.
