My SO says Thor is too big. Maybe he is, but what the heck could I do about it? He's not the alpha roo and my alpha is very vigilant about making sure Thor gets very few chances to mate. So really do I need to worry? He's six months old and weighed just shy of 11 lbs. a week ago. Here's Thor. I tried to get pics of him next to some of the hens for comparison, but if taking pics of one chicken is hard it's next to impossible to get two to hold still at the same time.
