Working With Bob Bennett Grey Lines in Practice
The Bob Bennett Grey Gamefowl History traces back to Bob Bennett's breeding program in the 1970s and 80s, where he was selectively pulling grey-colored birds from established hatching stock and fixing that color alongside specific type characteristics. The greys he produced carried a distinct structural look — heavier bone, a certain sweep in the back, and feathers that lay relatively flat rather than flaring. What made his strain stand out wasn't just the color. It was the combination of grey with a particular fighting style that tended to be methodical rather than flashy. I got into this line around 2004 after working with a few different strains that kept breaking down in the pen. I ended up picking up a couple of hens from a direct descendent of Bennett's original grey strain, and honestly, they were underwhelming on paper. The cock I bought looked narrow in the breast and didn't have the classic heavy stance you see in the old photographs. But he bred true to grey, and his offspring had a toughness that was noticeable within a single season. That's the thing most people miss when they look at Bob Bennett Grey Gamefowl History through photos alone — the visual references tend to show show birds or birds picked at their absolute peak. The actual working stock was far more variable, and a lot of what circulated under the "Bennett grey" label over the years was dilute or outcrossed material. If you're trying to trace or work with this bloodline, start by looking past the color. Grey is recessive, yes, but so many other strains produce grey birds. The Bennett grey is identifiable by bone structure — thicker shank bone relative to body size, a slightly dropped rear end, and legs that tend to set wider than the average gamebird. Feather texture matters too. The hairs are shorter and finer, giving the plumage a smoother appearance rather than the loose, fluffy look you get from a lot of modern hatchery stock.
One thing I ran into that isn't obvious from reading about this line: the fertility rates on older Bennetts from direct male lines can be inconsistent. I had a cock from what was supposedly a straight Bennett grey male that would set less than 40 percent fertility on good-quality hatching eggs, even when paired with proven hens. The workaround was switching his mating to younger hens — under two years old — which brought fertility up into the mid-60s range. Older Bennett grey males from those early lines seem to carry some kind of delayed reproductive decline, and if you're getting poor hatch rates with no apparent health issue in the bird, age of the hen might be the factor you're missing rather than the cock itself. The fighting attributes associated with Bennett greys tend to cluster around a particular pattern. They're not early aggressors. A lot of them take ten to fifteen minutes into a match before they really commit, and during that initial period they can look passive or even confused. The birds I worked with usually came alive with a steady, grinding pressure once they locked in. They don't typically go for the head or neck with the kind of speed you see in some Filipino bloodlines. The strike is more body-oriented, and the advantage builds over time rather than producing quick finishes. That's worth understanding before you invest heavily in a line if your goal is fast matches. A Bennett grey is better suited to longer, tactical encounters where stamina and weight distribution matter more than explosive speed. When it comes to sourcing, there's a real problem with documentation. Most birds sold as coming from the Bennett grey line have zero paper trail going back to Bob Bennett himself. What exists in written records is sparse — a few articles from the late 80s and early 90s in gamefowl publications, and some breeder forums from the 2000s where people tried to map out the remaining direct lines. The best approach is to ask for photos of the original breeder's flock, not just individual birds. You want to see the type consistency across multiple generations. If someone can only show you one or two birds and calls them Bennett greys without showing the broader picture, that's a yellow flag. The original strain had recognizable uniformity in structure, and that doesn't disappear overnight unless there's been significant outcrossing.
Another counter-intuitive point: the colour grey doesn't always breed true even within the Bennett line. I've seen grey paired with grey produce brown reds and blacks in the clutch. That happens because the grey gene interacts with other colour modifiers in the bird's genetics, and Bennett's original stock wasn't uniformly fixed for every modifier. If you're selecting strictly for grey colour, you need to breed from proven grey-to-grey pairs over multiple generations to stabilize that trait. Otherwise you're just gambling on what comes out of each hatch. Health-wise, these birds are generally robust. They handle confinement reasonably well and don't have the fragility issues you sometimes see in highly specialized fighting strains. The main maintenance consideration is leg strength. Their heavier bone and wider stance can put extra stress on the hocks if they're raised on hard surfaces during the growth phase. I switched my young birds to a sand and dirt mix for their first six months, and that made a noticeable difference in leg development and overall soundness compared to raising them on pure concrete or packed dirt. Here's the blunt part that most people selling these birds won't tell you. The original Bob Bennett Grey Gamefowl History represents a finite genetic resource. Every generation that passes without careful preservation dilutes it further. There are very few breeding stock lines that can be documented as direct descendants of Bennett's original flock, and those that exist are held by a small number of breeders who aren't particularly interested in distributing their best material widely. If you're serious about working with this line, plan on building your own foundation stock carefully rather than expecting to buy a complete, intact strain from a single source. Buy the best individual birds you can find, verify their type and fertility, and be prepared to cull aggressively over several seasons to lock in the traits you're after. It's not a quick process, and it requires honest record keeping. But it's the only way to get something what the original strain actually was rather than a vague approximation built from whatever grey birds happen to be available at any given time.
