I live in a suburb and can't have rooster or it will blow my cover. I have this one "hen" who doesn't act like the other two. 1) Makes frequent "honk honk" noises. Its easy to see how it could turn into "honk-a-doodle-doo" 2) Is agressive. If I am messing with the cage wire, tries to peck at my bare fingers. I offerred her my knuckle and she bit it, pinching it a bit. When I put on gloves, or open the door, the agressiveness stops. 3) Pecks at new objects in the cage. Like the shiny metal clasp. 4) Does not appear afraid of me. "she" is the easiest one to catch. 5) Of the three birds I bought, this one was the only one with a full tail (the others had tailfeathers missing) I dunno. I'm really scared that "she" will start crowing. These are black australorps by the way. The one that I am referring to is suppsed to be 2 or 3 months old. I've only had them for 10 days. Opinions?
