I have 8 chickens 2 golden comets, 2 australorps, 2 buff orpingtons, and one barred rock. The barred rock and one of the buff orpingtions are very friendly with me, but every so often the barred rock growls idk if its directly towards me, but she walks around growling. Both of the golden comets growl A LOT when they see me have treats for them, and even when i dont. Do they hate me? Ive had them since their were 2 days old, and now theyre 18 weeks =( what does it mean when they growl?
