I have a small flock of 4, young (between 3-4.5 months old) chickens. One of them (sex TBD) seems to lay low- then almost stalk the others, and charge them if they flap their wings wrong or move to quickly...if the one who was charged doesn't really respond, this chicken will go after whoever is closest next! Things usually calm down within a few minutes, and i haven't had any injuries yet, but every once in a while someone will stand up to my charging chicken and we have feet in the air and pecking and flapping... I'm a complete newbie to this (2 full weeks with my flock tomorrow!) so I was just wondering if this is normal behavior of a bully hen, or a sign of a rooster??? the other three seem happy to peck away all day, but this one always stirs things up!!! Help!!!
