Supposibly the Midget Whites were breed "down" by smaller slection & cull process, not breed dilution.
There is no natural small breed of turkey to breed into a comercial white in which to produce a "midget" or "bantam" size.
We who are breeding MW Turkeys are supposed to keep up this cull process, and cull any that appear larger than what they are supposed to be ( 20# max for Toms and 12-14# for hens, I believe)
Should I not cull to keep them small, they will eventually breed back to the standard sized commercial white.
I think you do the same with chickens..and maybe the same with Turkeys.
It is a little more involved than I have written here, but it "easy" to " bantamize" most chicken breeds.
Some breeders use this specifically to breed a better bird with less feed/time & space.
Once a nice type is attained, they then "enlarge" the birds back to their original size.
I have found it interesting, but have not had time to study it any further.
The idea of the Midget White, for example, was for the American Meat market to have a small turkey.
A bird that could fit on a spit, or in an oven without scads of leftovers.
I hear tell the man's true #1 goal was to have MW Turkeys side by side in the meat case (and near the same size) as that of Cornish X Broilers.
he desired a turkey eaten by an American family weekly, as chicken is, rather than just at the Holidays.
he also wanted them to remain a natural breeder, being lighter in weight.
Imagine that!
I have noticed that these birds grow very quickly, as stated, and attain their max weight early, in 4-5 months.
That is supposed to be goal #2, a turkey that matures in less time/with less feed.
Those of you who grow other turkey breeds..a question for you.
How long does it take to reach maturity weight with your breed?
I am still wanting to get some narragansetts..or Bourbon reds.....still trying to decide but must build more housing otherwise I would have gotten some already...
We are in a small (very small 1 room type) cabin and are building our home by cash, so it is buy lumber every 'pay day' kind of thing.
So building larger housing for turkeys may not be an option for me (DH would kill me)
