I reached into the outdoor brooder tonight at early dusk to move my birds into their sleeping area and the underdog roo leapt forwards and bit me! It wasn't a normal peck, he wrapped his whole beak around the side of my finger, bit hard and held on. I hadn't shocked them or scared them, and had been talking to them previously and as per usual, they all came over when I put my hand in. Just then this one little guy flew at me. Does this mean he's turning bad? The other roo is fine.
