I have four hens I am looking to slaughter. Two are just over 4 years old and two are just over 3 years old. It will be a first for me. They have pretty much stopped laying and are of no use to me. I would like to begin to learn how to slaughter some hens and raise a few for meat. I am just worried that because these hens are too old their slaughter will be useless as that their meat would be too tough to eat. If I slaughter them in the next couple of months will it be worthwhile or am I just killing for no use? It's taken me some time to come to the conclusion that I would like to do this. I watched the youtube videos and read the books and I think I'll have the heart to do this. Otherwise the other option is to just give them away on craigslist. It my venture worth while?
