I do the same! but I buy a whole chicken, not cut up, wash chicken then split the chicken in two ( or have the butcher do it) leave the skin on! (cut the backbone out then slice between the breasts)
Season the chicken, on top of the skin and under the skin, make sure to use a little olive oil after seasoning. I pour about a tablespoon in my palm and run over the outside of the chicken.
Grill the chicken on the top rack of the grill. Do not worry about charring the skin, because we don't usually eat the skin, we just leave it on for flavor and moisture protection.
When chicken is done use one 1/2 for that meal. let the other half cool just long enough so that it wont melt the Ziploc bag. When cool place chicken half in the Ziploc bag and seal. do not open until ready to use it. Putting the chicken in the Ziploc while it is still warm creates steam in the bag, therefore the moisture stays in the bag until you use it keeping the chicken moist.
heat in the bag, remove skin before eating!
Cooking and storing this way I ALWAYS get rave reviews on how moist and juicy my BBQ chicken is!
Best of luck Happy Cooking
