My husband and I wanted to raise meat chickens next year, preferably in some free range capacity. We live on 5 acres and will be building a 5' stock fence around our property (yes, I'm aware that a chicken will probably get out of that if so inclined). I was looking at meat breeds and apparently the Cornish X is the most popular but they seem to live such an inhumane existence. Is it true they grow too fast and have problems moving around and organ issues and all that? It seems to inhumane. Are there any other breeds with good meat production? Would a slower growing breed get tough by butchering age? Thanks.
