Yep...my son. He is selling the entire flock of Australorps (6 months to 4+ years) to a family in PA. It will be fun watching/helping him do his thing with the NN's. He seems to have a 'master-plan'.
I always knew (hoped) I'd have to roll-over one day.
Some of us may be using different concepts of "maturing." There is the time it takes to begin to lay, the time it takes to flesh out enough for meat, and the time it takes to finish out in growth/show potential. They are not the same time points.
My birds began laying at 4-5 months old but I did not consider them "mature" at that point. More like teenagers who finally got after-school jobs and took some of the pressure off the cost of raising them
The cockerels are still filling out at nearly one year of age, but the quality of the bone structure was evident from about 6 months. This is my first year with the breed. I'm guessing they won't have reached their full potential for another 6-12 months. So I consider these birds slow to mature, but they have been earning some of their keep in terms of eggs and meat since they were about 4 months old. I'm happy.

That is right. And everyone has a different breed type and ideal in mind when they say it.
My Catalanas are quick to mature, and a bit slow to flesh out. It will be interesting to see what they do this year, when I cross with related but long removed birds that were gifted to me this summer. My pullets would probably achieve better weights if they did not mature as fast as they did. Depending on how things go this year, I may start cutting their feed with oats while on range at a point. Slow them down a bit.
It seams to me that how a bird grows out is as important than when they grow out.
I do not have any experience with Minorcas, but it would seam that you would want them to take enough time to put that big frame on. That is comparing them to a lighter bird, and smaller boned leghorn.
Never had any Malays, but that seams to be a breed that you would want to grow out slow and sure.
I noted that some gamecock breeders let there stags range with little more than whole corn. They have to work to rustle up what they need. It seams that this is in part for practical reasons, but they also want them to grow out slower and more naturally. There is a belief that this makes for stronger more fit birds in the end. It is hard to argue with the results when you see that vigorous proud cock in good feather.
I noticed that some of my fastest maturing Rocks were a bit clumsy on the legs. Some of the more fit birds structurally were in between the slowest and fastest.
I would guess that Javas with their big heavy frames should be allowed to develop. It is not like they were ever commercial birds like a New Hampshire or Delaware.
It seams to me that there are more breeds that came on the scene before the commercialization of poultry meat. Back when dual purpose was as much about the old hens having enough meat on their bones to be worth stewing. Back when poultry meat was seasonal, and they extra cockerels were a buy product of the laying flock. Yes there was market fowl, but that was more for the city folk that could afford it. It was not long ago when a roasted bird was a luxury item.
All of this changed when there was a mass movement to the cities, agriculture became mechanized, and grain became cheap. Modern breeds like New Hampshires and Delawares followed.
Today they are all chickens.
I do think that when we develop these ideals for ourselves, that it is helpful to put it into perspective. The structural differences between breeds seam to have practical implications. It is what made one breed desirable over another at some point. Leghorns were more efficient, but the Minorcas laid bigger eggs. New Hampshires and Delawares were favored when grain was cheap and plentiful. They were more suited for intensive rearing, and they converted their big appetites into flesh. The Rocks and Reds being in between them and the older breeds like the Java.
When we are a breed enthusiast we do and should strive to make improvements. As long as we do not lose what advantages they might have had over another. There are some advantages to some breeds that grow a little more slow and sure.
Sarah, this post is not directed at you. I just rambled off the thoughts that I had when I read your post and considered your Javas. Of course this is all just opinion.
