My paternal grandparents use to raise chickens for a major chicken retailer. I saw them from the time they were tiny little chicks until they were adults loaded into the cages on trucks.
If you grossed out over nugget making don't go searching for how hamburgers get to your table.
I use to be Vegan but circumstances made that difficult to maintain. I say a prayer now every time I see a truck loaded with battery caged chickens on the road. Along with an apology. So sad.
