Q. Do you have information on how factories process chicken nuggets?

We do not have anything specifically about factories processing chicken nuggets. We do have an eBook, The Chaning Chicken : Chooks, cooks, and culinary culture that is about the Chicken Industry in Australia. Acces through EBSCO eBooks.

There are also two articles found through EBSCO Academic Search Complete that are relevant to the processing of chicken nuggets, 

Evaluation of two commercial methods for the detection of Listeria sp. and Listeria monocytogenes in a chicken nugget processing plant.
