All will be well, and that will be well is well.
Thanks! Very helpful.You are welcome, I am glad that my suggestions were helpful.
I would not say that capons of a said breed grow "significantly larger" than a standard rooster of the said breed, but a full grown capon is certainly larger and significantly more plump than it's intact counterparts.
The main idea behind caponizing is not growing large birds, the main idea is to improve the quality of meat. In the past farmers lacked the the luxury of refrigeration and hybrid meat birds. Many people outside of USA and Europe still prefer fresh meat, but keeping so many intact roosters is not feasible. Also capons fetch higher price than say a Cornish cross or an intact rooster. A capons meat is tender like that of a young bird, but at the same time it's flavourful like a full grown chicken.
So in conclusion, yes, capons are somewhat larger than a standard rooster of the same breed, but most are not "significantly larger", but they are significantly more plump. We caponize a cockerel for the same reason we castrate a pig, a sheep, a goat and a calf. A hog, a wether, a steer is not necessarily much larger than a boar, a ram, a buck or a bull, but they are more plump, their meat is better and they are easier to manage and you don't have to butcher them when they are young.
