So far the Cornish Cross are 3 weeks and the Red Broilers are 2 weeks. Both are doing fine and getting big quite fast. The Cornish Cross I had thought would get big fast and not be able to walk but they still can. They also will eat kale and worms outside on the raised beds. I am raising them on pasture a.k.a. one of my raised beds with a baby gate on it. I took photos but I can’t get the photos off the camera yet. My daughter Melody tells people that the meat birds eat and eat and eat and then explode if we don’t eat them. That is a good way of looking at it and she sort of simplified version.
