It varies on the bird, most birds are psychotic. Bouncing off the walls bonkers. Others who have culled against that and have heavily handled their birds have very calm males that are less likely to tear the crap out of their tails and combs in the show room. Then there are those that like to have an all-out flog fest each time you walk into the pens.
I have never been able to tame a LF brown leghorn of either variety properly for show. They prefer to hang upside down in the cage so I don't raise them anymore.
