How do I nip his aggressive behaviour in the bud? He is in a chicken tractor with 3 hens, he has suddenly started to fluff his feathers up and run at us, when I retaliate and go for him to chase him around and try to show him who is boss he tries to get me with his spurs. Just in the last day or two I have taken to keeping a long stick with me and then I chase him around the tractor with that until he backs off and stops going for me. His spurs are not sharp yet, he is only 9 months old and is gorgeous... but I don't want to have to be nervous every time I go to do their feed or collect eggs. Ideas anyone - I would like to try some behaviour modification before I send him heavenward... and how do you prevent this in future roos. He has always been a very laid back roo but I have noticed that he will spur the side of the tractor everytime the kids are near it, fortunately there is no way he can get to them. But I am working with him probably at least a couple times a day and don't like the attitude change.
