Thanks for the feedback.
So, for clarification, from Keeping Poultry and Rabbits on Scraps:
"Those who can get any quantity like rearing some cockerels... The cockerels want separating as soon as they can be distinguished, because they take the food from the growing pullets. When separated they can be kept on more bulky waste food, such as potatoes, whilst the more concentrated Balancer meal can be reserved for the pullets."
So this particular reference at least clearly seems to refer to cull cockerels or cockerels destined as meat birds--not potential breeding stock.
Honestly this idea is very appealing. We pay $25 per 50lb for layer, and the only chick starter we can get is $45 per 50lb. The going rate for farm fresh eggs here is around 7 dollars a dozen, for reference. So it barely "pays" to keep layers, never mind cockerels (however, there is no market for them and I am repulsed by the idea of culling them before they are of edible size, we just slaughter fairly young). So Any strategy that saves on feed is not therefor just a few cents here or there but has potentially significant savings over time. We have a small farm and can easily grow things like cassava yearround that can supplement in a mash--much like the "potatoes" refered to in postwar England. If we could raise cockerels more heavily on starch foods, greens, fruits, and scraps, it might be a game-changer--or at least make it feel less like a money-suck.
What is REALLY tripping me up is how to reconcile rearing cockerels separately with the fact that we are also breeding, and don't want to upset flock dynamics through separation/reintegration, or provide suboptimal nutrition for future breeding cocks. But in order to avoid this and still raise cull cockerels separately for a length of time needed to realize significant savings, we would have to make a selection among the cockerels when they were very young--and of course how the heck can you make a decent selection at six or eight weeks old? You see the dilemma, of course...
Perhaps the best compromise might be a two stage selection process: to keep two or three (or four) of the "most promising" cockerels with the pullets and then narrow the selection further later. This lets you avoid "wasting" prime feedstuffs on the obvious culls, while still leaving some room to select later on. (it also would reduce that feed competion with the growing pullets sooner obviously.)
In other words, saving on feed may have to take some precedence over selective breeding, but of course we would ideally like to have something of both--and at the very least hedge our bets in case future breeders don't survive to breed, or turn out to be horrible man-fighters, or for whatever other reason prove unsuitable.
Surely there must be some sort of precedent for something like this: in earlier times most chicken keepers were also defacto breeders as well and had to produce broilers as well as breeders, there was no cheap pre-mixed feed subsidized by government money and fossil fuels, grain was grown and processed by hand and much more precious. Surely open ranging helps, but this is not a viable option for us. Im sure people did all sorts of clever things to make the best use of resources possible. And back when caponizing was more widely practiced, it meant that people had to be able to make some degree of selection of cockerels from a VERY young age (with no chance of changing their minds later in that case)! Trouble is, I dont know any ancient chicken farmers to ask about it, and googling has not turned up much...
What do you all think tho... Any thoughts on that...? Sorry for the long post... sometimes I just get on a roll...
