I live in New Hampshire. I have been raising layers for a few years now (only 3 hens per year). I wanted to branch into raising meat hens as well. After reading several threads on the messiness of raising the two kinds of birds together, I am rethinking. Someone mentioned "all-purpose" breeds that can be raised as layers and for meat. What are some good all-purpose breeds? At what age would each start laying? and at what age is best to slaughter for meat (before the meat gets too tough and only good for stewing)? Thank you!
