My 13 week buff Orpington hen has been showing aggressive traits in the past few weeks. Not towards the other chickens though. Mostly towards my dog who she has grown up with since we got here at about 1 week old. She also likes to attack the outside of her chicken coop... she’s a strange one, but I thought buffs were supposed to be on the nicer side of the chicken breeds. Is her behavior normal? Any tips for what I could do? Orrrrr... maybe she is a he?
