OK, I have a question and a confession

I am lax about rotating food in my freezer and I think I’ve come to a point where I’ll have to discard some things. I admit I don’t cook a lot for me – I bake cakes for others and those supplies aren’t around for enough time to be rotated but I took a look at both my chest freezer and the freezer portion of my fridge and have become disheartened.

I have chicken(s) in my freezer since 2015. Are they any good to thaw/eat? I should say I have other meat from 2015 too, none of it freezer burned but I have meat from 2015. What do you think?
