I'm wondering at about what age I should be considering butchering some of my Red Rock (black sex-link) hens. My husband and I got 12 chicks at the end of April with the intention of only keeping 3 or 4 over the winter, and butchering the rest for meat (we got only hens just to make sure we didn't end up with 2 roosters and 10 hens, or something like that
)
The hens are about 13 weeks old now, and they're starting to look pretty decently filled out. Should we wait until they start laying, or is it better to butcher them before then?
