your best bet is to go to a chicken show and find the birds you are looking for- keeping in mind they are sometimes vaccinated and carriers of disease. (keep them seperate from other chickens). OEGB's are probably the most widely shown breed, it shouldnt be hard to find a good trio for around $60.00.
when you order from a breeder, order at least 40 chicks to get a "good" trio, or 120 chicks from a reputable breeder to get a trio that will place in shows. most breeders run this ratio when selecting their show birds.
the last method would be to order 20 or so chicks and select a good trio, then breed for about 3 years to get to show quality.
crele is really hard to get right, they should have a barred and not cuckoo appearance (lines should be straight in the feathers). old english type, with proper spur set and head shape is hard to achieve. keep in mind there is no such thing as a perfect chicken.
