Feed them as you would any other Hertage breed chick.
4 to 6 weeks chick starter or starter/grower
for layer
4-6 weeks to about just before laying grower
at about 24 weeks they should start laying
layer ration with extra calium in the form of oyster shell or egg shells.
for meat birds
4-6 weeks to finish grower
for meat birds that last 4 to 6 weeks before butcher you can switch to a finisher ration. Generly you won't find a finisher ration as bagged feed. some feed mills can custom mix it, there is several example of what some backyard growers us on this forum or I have seen some after googling for "custom chicken feed mix".
For a finisher for heritage meat birds we tend to use a bagged grower feed. Then add roll Oats and cracked corn, I can't tell you the exact mix, not because it's super secret but because my wife mixed the feed
If you can free range or have the chickens on grass, you can always have some patches of tall grass to cut and bring to the chickens.
Now you will find many variation of this feed schedule, and adventualy you will develop you own.
Although a lot of people advocate butchering heritage meat birds at the 15 weeks range. This is done to produce a bird that is good for frying by modern standards. we believe this is not long enough for some types. Plus we don't fry chicken. If you wait until at least 28 to 30 weeks you will have more meat on the birds.
We had one Buff Orghington Rooster that we waited until he was a year old before butchering and he was tasty broiled.
