I take it you are refering to Red Jungle Fowl ? If you mix breed banams they nearly always revert back to this type of chicken , or look very similar to it !!! Years ago I kept all sorts of chickens , bantams , pheasants , guinea fowl , quail , and even a few real Red Jungle fowl . I think mainly you only need a licence for dangerous breeds ie ostrich etc, or maybe very rare breeds. At the time, 30 years ago , nothing was needed . There again 40 years ago I bought a couple of baby crocodiles for 10/- each ( 50 p ) , and I was only 10 at the time . I kept them in the garden shed , fed them on dog food , till my dad found them ....they then went to live in London zoo ....
So I doubt you would need anything if you can still buy them ? Another good one to breed for fly tying is the Golden pheasant , as long as the carcase is used for food ? I would hate to think of any bird just killed for its feathers....I sold plenty of their feathers and napes for fly tying , (my dad went to fly tying classes so had plenty of willing customers
) . The carcus we used for food , not much meat on them though . Common pheasant were much bigger as were guinea fowl .
