Going to buy my first piece of LC (yay) and I intend to use it primarily and often for roasting (whole) chicken. I'd prefer to get a round shape for additional versatility, and don't know if I should buy the 5.5 or 7.25. Weight is not an issue. Would a 4 to 5 lb chicken be crowded in a 5qt round? Would it get lost in a 7.25qt round with too much space on either side? Any opinions and experiences much appreciated - sorry if this has been covered before, but in my research I did not find these questions answered specifically... and as for color, I'm thinking mustard yellow!!
