I read in " Raising Chickens For Dummies " that is not recommended that chickens free range until a good egg laying pattern is established. My RIR and Barred rocks that are 10 weeks are getting a bit antsy in there run. I have intended to let them free range,but have been holding off until they start laying. I don't want to have a Easter egg hunt on a daily bases. Has anyone let there chickens free range before there old enough to lay and not had a problem of them using there nest boxes once they do lay eggs?
