    Just like with humans, there are an infinite number of variables that just make this impossible to answer. Things like their place in the pecking order will determine how much and what food they have access to. Their genetic disposition will have an affect because their parents may be naturally smaller or larger, plus any genetic illnesses that may occur, such as tumors. The weather will also affect it, and that has a strong correlation to their feed. A feed with low corn concentration, for instance, will require them to burn more of their body mass in order to stay warm during winter.

    Something as simple as the feed can make a huge difference. Take fermented feed, for instance. One study was comparing the weights of regularly fed broilers versus fermented fed broilers. The fermented feed caused a slower growth development, but provided for a more nutritional and healthy growth resulting in 2 to 4 weeks additional life. The regular feed, however, caused them to gain weight abnormally fast, at rates that prevented their legs from properly developing. You can find the study in the first few pages of the Fermented Feed for Meat Birds thread.

    Just some things to remember. And the size of the chicken should be of far less concern than their overall health. For most, the ultimate goal is to provide food, either through the eggs or the meat or both.
