Good but a 4 pound chicken is a LOT of chicken. I would suggest about a pound of chicken thighs and a pound of chicken breasts. Maybe 2.5 pounds of chicken total.
Edit: I use about 1-1.5 pounds or one package of chicken thighs and 1 chicken breast now. Still a very meaty soup. I also pull the chicken skin off most of the chicken to make it easier to skim later.
