Some of the many articles about it:
The notion that wolves fight amongst each other and the strongest becomes the “alpha” and the weakest is the “omega” and all that, is a misconception that has been debunked ages ago, and even the author of the study who called them “alphas” in the first place is pleading with his old publisher to stop printing the dang book already so this misconception can finally die out.
Wolf packs are more or less just families. One “breeding pair” and their pups, which often stay with their parents way into adulthood.
nah chickens are just terrible terrible creatures, even if they have all the space they could ever want they will still peck each other and will blithely peck flockmates to death if they have a wound.
