I have had a variety of roo breeds and have found them all to be great in disposition and in doing their jobs. My fave is my Partridge Rock roo because he is the strong, silent type...rarely crows, gentle but firm with the ladies, beautiful to look upon and heavy built.
Here is a young White Rock roo that someone gave me a couple of weeks ago, probably 5 mo. old. He is gentle....so gentle that he has taken over brooding my meaty chicks~literally.
I have found you really can't go wrong with the WR hens~they are tops in my book~and with the Plymouth Rocks of any type(White, Barred, Partridge, etc). They are exceptional birds in all ways.
