I have one with just three hens. He is disabled now, but he was fine with just three before he got hurt. He would of course mate any others that were around and two others would sometimes join their group. Another had three to start, but another joined them later (One of those two that sometimes change houses. Can't keep them in if they decide to get out). They only get bare when they are molting. I think he would do better with a few more.
The first is a bit smaller than the hens, the second a bit bigger. Might factor in somewhat.
