I bought two of what I believed to be Plymouth Blue Rock pullets last April. They both turned out to be roosters. I have included a pictures of the rooster and identification card at the Tractor Supply store where I bought the chicks. I know that sometimes mistakes happen, so I am fine with these being roosters. My questions are: Are these really Plymouth Blue Rock roosters and if so, would the experts on this forum recommend breeding this rooster with a Leghorn, New Hampshire Red, or White Rock if my goal is to have good dual purpose hens? Thank you in advance!
