I tried a rooster for a month. I think he probably would have ended up being a really good rooster eventually, but I wasn't going to wait it out. He was simply to rough on the girls (lots of feather loss on one, an occasional bloody comb on another who wouldn't submit). Two hens seemed to do well with him, two didn't, and I rarely saw him take on the lead hen. He was about 9 months old and very hormonal, and I only had five hens, so I'm sure that was part of the problem. I will say that he was very protective of the girls. However, my lead hen acts in a similar fashion with warning sounds, and my girls always seek cover when hawks are nearby. So it's not like hens will just sit around like...well...like sitting ducks (lol) when predators are nearby. Unless she ends up with a very gentle, gentlemanly rooster, she may end up needing chicken saddles for her hens, since she only has six.
