Another newbie question, maybe you can see where I am going... Is there a standard/consistent curve of weight gain on meaties in that at an age of 4-weeks, those who are heaviest in weight will likely be the heaviest at harvest time of 8 weeks? Anyone done these types of weight charts? If so, I would like to keep back a few of my hens for some breeding experiments, but I would want to modify their diet to preserve for longevity (get them into Jenny Craig) to be able to sustain egg laying for a longer period of time. Second question; how do you guys leg band for your experiment/monitored birds? What is the best source/practice?
