I will be getting a bunch of rhode island reds and barred plymouth rocks. I would like to use the roosters for meat. Can I feed them the same as my layers, our should they be separated? I would really like to only have to separate them when the time comes for processing. I'm so new to this! Can they all live together and eat the same things if they will be processed at 20 weeks or so. Any advice for a mixed flock of layers and meat?
