Last night I let the chicks (3 wk olds) out of the brooder to run around some with my 7 week old pullet "Chopstix". She's a little bossy, so I was sitting with them within arms reach and I'd 'peck' Chopstix with my finger each time she'd chase a chick. Anywho- the little roo's started standing up real tall and kinda puffing up and then would run at another little roo, flapping and squaking. Are they already trying to establish a pecking order here? It really was quite funny to watch the little guys try so hard to be big! One little guy in particular was very aggressive, he would even charge at Chopstix and once even jumped on her back. (she did not appreciate this). Incidentally, he has the largest comb. Does this make him think he's king??
