Tired old Rooster

Imprinting puts them as on a par with you. Subject to their laws. Yes?That’s what I believe.
I have received multiple “man fighter” roosters and bred them. Their offspring, grand offspring, great offspring, ect. don’t exhibit the trait when raised on my farm. If sent off farm as hatching eggs, they may become “man fighters.” The common denominator seems to be artificial incubation and close coddling in early chickhood. On my farm, they’re either hen raised or (if artificially incubated) hatched in a dark barn where I only interact with the new chicks behind a flash light. I make myself an object of fear instead of comfort to them. Then later they begin to associate me as the bringer of sustenance, but I’m never a mother to them.
In artificial incubation, degrees of presence, contact, and handling vary between people and batches of chicks. Furthermore, the imprinting instinct is stronger or weaker between breeds and individuals. I think all of these variables contribute to the apparent randomness of when roosters grow into being man fighters. It appears random because the variables make imprinting sporadic. But I have little doubt imprinting is the cause. In birds less domesticated than chickens, such as heritage domestic turkeys, imprinting is much more obvious and predictable, resulting in gobblers that want to fight humans and hens that want to be bred by humans.
