yep, dark gray feathers are pretty good natural camo - so natural, even the archer/hunter mostly can't see 'em in flight, or find 'em when then go astray.
i've not tried to dye goose feathers, dunno if it can be done and if it'd remove all the natural oils that make it so good in the first place. don't intend to bother, either. i like the idea of all natural fletching, particularly on woodies.
what can help heaps is a large, bright crown wrap and florescent nocks.
i'll still use be using canada goose feathers, none-the-less!
UPDATE - ah! the answer for me is fur tracers!
goose feathers are very water resistant. here's the results of a 5 minute running water feather test guess which feather is the turkey?
