This is my first time with a rooster. I'm not sure if he's in love with me or if he's sizing me up. I don't understand his behaviour. He is 5 months old and is starting to becoming interested in the ladies. He kind of purrs at them while he walks sideways up to them and then grabs them by the back of the neck. I took this as some sort of mating ritual. Now when he sees me coming, he purrs and puffs up (not hackles up) and walks side ways up to me. I'm not sure if this is a warning or if he wants to show me some affection. What do I do with him?
