"Good" egg production was much different (150 eggs a year was amazing back then, now it's considered below average). And while egg laying is genetic, nutritional science has come so far that is a big contributor.
If you want maximum production out of your birds, or indeed even what we consider "normal" these days you need to feed them a properly (professionally I might add) mixed diet and NOT rely on foraging or scraps to feed the birds. It's just that simple.
Too true, and there's no way around it.
However, most people say they want full production, but most folks don't actually need it. If you have hens giving you 150 eggs a piece, and you're just focused on your homestead, that's a lot of eggs.
Small and medium eggs were available, but so were large eggs. However, you got the eggs of the breed you had, and it didn't really matter. If you go to old cookbooks like the
Joy of Cooking, etc..., in the appendices they often have egg charts that speak to equivalences. This is why the old egg-scales were so important. Recipes were
written for large eggs, but many folks didn't have access to large eggs. If you or your egg-producing neighbor had Hamburgs, you had lots and lots of not large eggs. Still it's just a matter of weight. A large egg is 2-2 1/2 oz. So, if you need 4 large eggs for a given recipe, you really need approximately 9 oz. of egg. You would have just weighed out nine ounces of egg on the eggs scale, maybe five or six Hamburg eggs, and off you'd go.
I think it's a whole process of rethinking what you need and rethinking what chicken is. You're leaving Perdu; Perdu dies or it's rather "
perdu" (lost). It's not just the end product but the entire rhythm. Marans are actually meat chickens. They're meat chickens that lay pretty eggs. If we're finding that their not well fleshed, that doesn't make them egg-birds; it makes them bad meat birds. However, they just need to be selected for fleshiness; it will come.
You can make due with one "dual-purpose" breed, but, if you want cheaper production, I'd keep three or four pairs of meat birds, i.e. most dual purpose breeds, and then I'd run a larger flock of egg-birds. It really is time to revive the Hamburg. Mediterranean and most Continental fowl are the way to go--honest to Pete. If you want meat birds, keep one breed and one variety of a "dual-purpose" fowl and keep three or four pairs. Breed them like rabbits, but don't keep more than 4 pairs. For your egg production keep pens of Hamburgs or Lakenvelders or Campines or Anconas or Andalusians or Buttercups. You'll drown in eggs and they'll consume 1/2 of what the same number of "dual-purpose" fowl would eat. When we were doing the egg markets, it wasn't with Dorking eggs; it was Anconas, dozens and dozens of Anconas. They just shell them out.
For homesteading, keep four pairs of dual-purpose and four sextets of egg-birds. You're set for life.
