Some say that the original E.S. Hatch blood was bred by Hatch's friend Judge Leiper who got them originally from a man in Huntington, Long Island. They were supposed to be a Kearney Whitehackle, Kearney Brown Red cross. Leiper also bred a 4.12 ginger-colored cock from Duryea for several years. Hatch told Ed Piper that around 1900 he got some dark red, green legged fowl from a Mr. Cassidy (or Lynch) of Huntington, Long Island, NY, and later several times through the years got more of that blood. They were dead game, hard hitting and tough.
He bred a black red cock from Harry Genet of NY, breeder of the Genet Pyles over the Cassidy (some say Lynch) hens. This was the foundation blood and Hatch made many crosses and it is said that at the time he gave them to Mathesius none of the pure original stock was left. Hatch was well acquainted with Mike and Harry Kearney, Jim Thompson, Joe Crossin, J.W. E. Clark and Simon Flaherty. It is said they often loaned each other brood fowl.
When Jim Thompson died, Hatch got the choicest of his Mahoganies. When Mr. Clark died, Hatch got the best of what he had left. These came mostly Roundhead and were probably part Duryea, which contained Boston Roundhead blood. Hatch and T.W. Murphy were close friends and he had some of the Murphy blood. He crosses Foley's Gingers (that Murphy gave him after buying all Foley supposedly had). They quit and discarded them. He bred a Stegmore cock from Bradford, and then discarded those. Clarets and others from Dave Ward were bred. Blood from Morris O'Connell was added as well as good Morgan blood from Billy Clarkin. He bred fowl from Simon Flaherty.
Most of his cocks were yellow legged and dark reds. However, some came green legged and came all shades of red, some a dark red, some a rustly red, some a brownish red and others a sort of maroon color. They were strong, hard hitting cocks, not only dead game, but tough and could take a lot more than they could dish out as many of them were low headed, dumb and poor cutters.
In 1931, Hennie Mathesius went to work for Hatch and carried his fowl with him, which were Morgan Whitehackles, from Hill, of New Jersey, some Lowman blood and some Gull/Morgan crosses. Some of these were crossed on the Hatch fowl and though their progeny looked about the same, they fought better. They lost a little of their power, but became higher headed, better cutters and won a larger percent of fights. Some think they lost their extreme gameness, but I think this was the case only in some yards. Hatch gave all his fowl to Mathesius, who sold them to C.C. Cooke, of Oklahoma, who soon became partner of E.W. Law.
