Some information about the "Exchequer Livornos"
When analizing the White Livorno, it's dominant white.
Bad exchequers look like mottled blacks.
Good exchequers look like very leaky (black) whites.
Without good breeding exchequer becomes a mottled black.
Exchequer is war between black enhancers and leaking pure dominant white added with mo
An exchequer must be a silver bird.
Begin 1900 on the property of a farmer in Scotland in a flock of 4000 white leghorn chicks there were five with black yellow pluff.
Before 1900 there was crossed only once a black Mincorca to the white Leghorns.
That Minorca must have carried the invisible "mo" (single doses of the recessieve gene mottled) and crossed with a white leghorn.
Two white leghorns both split for "mo" were crossed etc ... nobody would notice mottled on a white bird.
If that Scotish farmer had cooked those "mis-colored" white leghorns there would have never been exchequer ;-)
