Jimmy has raised most all of the lines through the years so I believe he has the most knowledge on the different lines.
Thank you for the link. I found the RIR Experience page to be very helpful. I noticed he didn't mention anything about the Underwood line from Hutchinson, but did mention Trish Dusil's birds, which they both got directly from Underwood. So i am assuming they are the same? From reading the about different lines of Rhode Island Reds it seems that every line has its pros and cons, you just have to pick what matters to you.
