Well, here is the list from ALBC... but you have to take it as you will. I believe their census is scewed. Also --- very few hatchery birds meet the breed standard, so it's hard to tell what he got. If he's interested in preserving rare or endangered heritage poultry, have him look up the breeds & see what he's interested in. We liked using
Henderson's Breed Chart even though it's not perfect -- still a handy tool & has links to pics from Feathersite.
Some rare breeds are much more rare than their ALBC status claims. Looking for certain colors of Dorkings, like white or cuckoo is unbelievably difficult. Even the "common" colors like Silver Grey & Red are not easy to find. Some hatcheries that have them have decent stock -- others not so much. Part of it depends on where you live & if you have local breeders with rare breeds.
