Rinse chicken inside and out well. Roll the lemon on a flat top to soften, and pierce well with a 2 tined fork. Place the lemon in the cavity of the chicken and place the chicken in the crockpot.
Mix the honey and the orange juice together and pour over the chicken. Cook on low until done. When you take the chicken out of the pot, remove the lemon very carefully, it will be hot, and squeeze the juice over the chicken.
