The breeds we have had both sexes:
Buff orghington eggs not to bad a little smaller the the large ones from a red sex link, they also have an odd shape (more like a football, or rugby ball) to the eggs. In a weeks period they lay 5 to 6 eggs. Meat was good even a for a year old roo, the two boilers for this year we haven't eaten yet be they were as large dress as the other broilers this year.
(4 meat 1 layer)
Red sex links, Very good egg layer they lay just about every day, very poor meat bird. the broilers dressed at 2 lbs while the rest of the meats birds this year were around 3 to 3.5 lbs. The Males temperment was the worste I have seen.
(6 meat, 2 layers, 13 pullets)
Barbed rock, Not to bad an egg layer, size is almost that of a red sex links, The dressed weight was in the 3 lb region. There temperment was not to bad most of the time.
(3 meat, 3 layers)
Although we haven't had them as layers Turkens were kind of nice to raise and butcher. while we still had all the broiler together the Senior turken's kept all the other breeds in line and there was not to much fighting. They were the easiest to plucket and seem easier to cut up. The naked skin around the neck made it little harder to get to the crop.
