Yes. I don't rotate but some do. I have a chosen male with chosen females for the traits I'm looking for. The fellow who started this thread Bob Blosil who unfortunately passed away a few years ago but knew his birds. I believe he did rotate his male of choice. I think he actually posted on it. I usually have two breeding males for each breed I have. I have rotated but don't make it a practice. Good luck and have fun...And I see some say use the same cock rotated through all three pens or I could use a different cock and then use uncle/niece or aunt/nephew pairings the next year?

This is for Rotational Line Breeding White Plymouth Rocks but will work for other breeds as well,
