Pecking Order or Parasites?

[Wakkibanana]

Hey! I am a new time chicken owner, and we bought five chicks a few days ago. One of them is pecking at the other chick's beaks. I know that chickens establish dominance this way, but she seems to only be pecking their beaks/base of beak. Is there a chance that there are parasites there that she is eating? Or is it just establishing the order?

 

[chickens really]

Pecking order starts to be set when the Chicks are around 3 to 5 weeks old...New Chicks peck at everything...It will stop once the Chick gets older....Adding logs and little perches cut back on boredom....Also dust bath area.....


Cheers!
