What does pecking order mean??

really?????

whoever is dominant will "peck" the submissive chickens..

 

That's how chickens establish heirarchy- one will be the dominant one, then the others follow in order until there is a lowest rank one. They fight, peck and generally bully each other. The dominant, or alpha one, decides who does what when, and if somebody steps out of line they are punished.

Just like a job, or a pack of dogs, or pretty much any other group.

 

In her book Hobby Farms Chickens: Tending a Small-Scale Flock for Pleasure and Profit, Sue Weaver describes the pecking order very well:
"In any flock of chickens, there are birds who peck at other flock members and birds who submit to other flock members. This order creates a hierachical chain in which each chicken has a place.
The rank of the chicken is dependant upon whom he pecks at and who he submits to. He ranks lower than those he submits to and higher than those he pecks at.
A flock of chickens generally have their pecking order up and running by the time they're five to seven weeks old.
Pullets and cockerels maintain seperate pecking orders within the same flock; as do hens and adult roosters.
Hens automatically accept higher ranking roosters as superiors; but dominant hens give low-ranking cocks and uppity young cockerels a very hard time.
In a closed flock with an established pecking order, there is very little infighting. Each chicken knows his or her place, and except among some roosters, there is suprisingly little jostling for position. Dominant chickens signal their superiority by raising their heads and tails and glaring at subordinates, who submit by crouching, tilting their heads to one side, and gazing away - or beating a hasty retreat."

 

Watch the birds and you'll see certain patterns emerge: some birds always eat first, come out of the coop before the others, get more treats, and lead the others around the yard. Those tend to be the higher ranking birds.
