We are currently raising a batch of 12 week White Rocks, currently they are doing well and I am happy we picked the dual purpose as I accedently turned one into a pet(she is currently sitting on my shoulder) Currently we are 6 weeks(or so) into the project. I know with the cornish crosses we could be butchering now. What do you prefer with a finished bird? Slower growing 12 week birds or the 6-8 week fast growing cornish crosses? Also, has anyone ever had any experience with Hubbard Mt. White and Van-Tress Crosses? I ordered 10 Van-Tress to pick up May, 30th and 20 Hubbard Mt White and 20 Van-Tress to pick up June 26th, for 4-H market birds. I am figuring do an experiment to see which grow better and which the judge prefer. I believe they order them from Townline Hatchery and/or McMurrary.
