Recipe: Nona's Italian Country Chicken

I tried this recipe and the amount of chicken to use is confusing. It instructs you to quarter 6 chicken breasts. Is that a single breast so the piecse are bite size? I cut the breasts into 2 halves so that I had 12- 3 inch square pieces which seem to work but I can't visualiza cutting one single breast into 4 little pieces and baking for 45 minutes. Any comments?

Our instructions were to cut the chicken breasts in quarters, but halves work too. The recipe calls for 2 1/2 pounds of boneless chicken breasts.
