my Pilgrims were huge birds, much bigger than I anticipated. They were also relatively loud and difficult to approach, they showed some more defensive behavior than I would have liked. They were both male and though best friends, would regularly squabble for dominance among themselves (their yard mates were 3 ducks). They would have dressed out really nicely, being so large and white. But if you go the pilgrim route, get a larger group with more females than males if you can. Raise them from day olds and make your kids handle them a lot. This will ensure they become accepting of you all and not flightly when they free range.
FYI, my no frills tolouse is small compared to those pilgrims (all came from mcmurry hatchery) and she is quite easy to deal with, not agressive, but very watchful for her duck flock. She does well with strangers and children, I don' think she really distinguishes between kids and adults, generally she will take food from kids easier because the children are more excited to feed her. She has lovely white down on her undebody and though I couldn't eat her unless it was an emergency, I'm sure she would be very flavorful and dress out relitively nicely.
