I have had two batches of RIR's. The first batch, while laying great amounts of large brown eggs, they were the worst cannibals I have experienced. They were not friendly, and were very mean to all other birds, however the second batch, which includes a rooster, is quite the opposite. They have been great flock mates, have not picked on anyone, and the rooster is not aggressive. He is persistent in servicing the hens, however he doesn't over do it like some others I have had. These also are very economical and lay well for the amount of food it takes to produce them. They forage well and (so far) have always laid in the coop, so I do not have to search for eggs. I will continue to raise these as long as they are like my second batch.
