I have meat birds that are ready for the freezer. Actually where ready about 2 weeks ago. We put some in the freezer then. The little kid in me came out and I wondered if I had a 7 week bird at 6-8 pounds what do I get at 12-14 weeks? Well to answer your question you get a basketball or a beach ball with feathers. I am guessing they will run about 12-13 lbs. Now for the problem. I have one roo that is having trouble moving around now that he is so fat. He will get up but doesn't seem to quick to move unless I make him. Should I go ahead and cull him? Will he be ok to eat if I do? Going to do this today if it works out. let me know!! Thanks!!!
