How long can a meat bird live if you don't cull it? Someone bought me 6 chickens without knowing they were meat birds. Being as though I don't cull any of my chickens, I can't seem to process the thought of culling these meat birds. I know that their life span is short based on all of the problems with them (leg problems, etc.). So, I was thinking about just keeping them around until. How long can expect them to be around? Anyone know?
