I missed where it was mentioned where the Dominique would grow faster than a NH. They shouldn't, but really I know nothing of Dominiques. I do find them interesting. I do know NHs.
I think you get my point on size. This thread is called Farming and Homesteading Heritage Poultry. I think they are two different things Yes, esoecially when you explain your view. I like my NHs, and they fit me. I would not recommend them as homesteading birds, because they are not low input. Different birds for different times. I see breeds like the NH and Delaware as the link between before and now. These two came about as we became serious about large scale intensive rearing of poultry meat. They were it in their time. Their short time. I will say that it was more of a farming, product oriented view that I was discussing the Rocks, Reds, etc... I'm with you on this.
I cannot help but consider the what goes in and what comes out part. When I think of the word homestead, I picture a system where commercial production is the anti thesis. Many of the more modern breeds were developed when grain was cheap and plentiful. The system depends on it, and NHs and Delawares are commercial birds of a different time. I picture lighter more active breeds for "homesteading". That would be like going back in time to me. A time where poultry meat was an extra and seasonal. I like the Mediterranean breeds for this, and to me the Dominique are a bridge between the large dual purpose American breeds and the Mediterraneans. From this view, this is quite sensible.
I like to mention this, because I have come to appreciate the lighter more active breeds. I have not understood why there is not more interest in the Mediterraneans. I probably bought into the flighty notion myself. I get 25% more eggs from my Catalanas and they eat a good bit less than my NHs. They have 100% more personality. I have been surprised to realize that they are more hand tame than my NHs. The cocks/cockerels are especially bold. They have a way about them that wins you over.
