I have 4 hens that are almost 2 1/2 years old. Barred Rock, Red Sexlink, Rhode Island Red and a Buff Orpington. Will the meat be tough since they are older? If I wait until this spring will the meat be even tougher than if I do it now? I live in town and are allowed to have 8 hens. I'd like to see if the Buff Orpington would be willing to raise some chicks next spring that have already hatched. Do you think she would or would she just try to kill them? I'm trying to figure out how to do this without being out of eggs. Thanks for any help.
