I have 5 hens,all 16wks old. I have yet to let them free range but would like to do so on days or hours that I am home. Someone told me i missed the boat,that its too late to start free ranging them. Said i should have F/R them from the beginning. Is this true ? If not, what is the best way to do this ? I don't want any of my girls wandering off and getting lost r being stuck out all night. We do have foxes and racoons. Thanks for your help.
