There is NOTHING in that post of Bee's that says to "beat or traumatize" the bird. When she says "give him a good smack", it's just to tap the fluffy backside to get his attention and get him moving.I agree, and it has worked for me with not one, but two troubled roos and my rooster I have right now and have had for 3 months now is still people friendly. I find Bee's method to, well, be very harsh and more of a last resort. Anyways, doesn't the 5 freedoms mention the freedom from harm and fear? I do walk over my roo and move him out of my way by nudging him with my foot, but I don't beat him or traumatize him to the point he can't eat, mate or even crow around me.
Some people can't get close enough to their roosters to pick them up and carry them around, or are to afraid to. This is just another training option that has been known to work. We all have to do what works best for us.
