Newbie to chicken-raising! I have 14 chicks of various breeds that range from near 4 to 6 weeks, and so far, I have only identified one cockerel, Rudy. He is a RIR who is the largest and appears to be the oldest chick of the bunch. He seems to be already exhibiting quite a few roo-ish behaviors that I am trying to understand. He will peck the other chicks if I am holding them! He will pace around me, giving me the one eyeball stare, peeping incessantly, and he will sneak in and attempt to peck them on the feet or even on the body if he can't get to their feet. I am wondering if he is "jealous" of me or if he is already expressing possession of the other chicks?? He is docile otherwise and will allow me to hold him, so I am just curious if this is normal behavior or if it is a sign he will be "mean" later, since he hasn't even gone through chicken "puberty" yet lol.
