I mean, the roast chicken you get from supermarkets?

I want to make lunches for Shel for work from now on, eating healthy and being a good partner etc etc, and know that if we buy a large roast chicken theres enough for 3 meals, but not exactly sure if it would last (buy on Thursday night, eat chicken Thursday dinner, Friday lunch, Saturday lunch).

Do you think it would last? Can you freeze it? Or should i just buy a smaller chook and find a new lunch for Saturday?
