I was thinking about grinding up some chicken breasts and making my own burgers. I have an old hand grinder I use for my deer and I was going to buy around 40lbs of chicken breasts to grind and make burgers. I also have a burger press that yields 6oz burgers, which would be a perfect portion size.

Has anybody ever made these before? My main question is about freezing them. I freeze my deer patties and never add anything too them, but I notice when stores freeze products that add a bunch of salt and water. I just freeze without adding anything too it. Will this impact the nutritional elements of the chicken by freezing it and recooking it? It is a pain to clean the grinder, so I don't want to make them every week and would prefer to just do an month at a time.
