Is my chicken good to eat?

I bought the chicken on Saturday, and it was put in the freezer then taken out Sunday morning. It was out ALL day Sunday to be thawed and then put back maybe after 5pm or a little later. It's been sitting in the fridge for a copy of hours.. it's not yellow but the top piece of the chicken cutlets is a little yellow. It doesn't smell but if I get EXTREMELY close to it to smell it, (like nose touching) it has a small smell of milk.. almost. I'm not sure how fresh chicken is supposed to smell. I was wondering if it was okay to eat?
