I usually can only tolerate waiting until about 5 months with mine. I waited until 6 months with another so that I could do several at once and the increase in meat was minimal; mainly he just had more fat and got an extra month to be a pain in the butt.
Since most of my birds tend to be bantams, I use them for soup meat. I only get about half a pound of meat per bird. I put 3-5 in the stock pot with water and cook them low and slow for several hours until all the meat falls off. I collect everything out and separate the meat to cook with immediately or freeze. I add the bones back to the pot (sometimes) as well as vegetables like onions, carrots and celery and herbs/seasonings and continue cooking it to make homemade broth, which I also then cook with immediately or freeze.
