I have some 3 1/2 year hens, some 1 year old and some in between. I do have about 30 pullets that will be laying soon. What I want to do is take the older hens and put them in a seperate pen one at a time. I want to find out who is laying and how often. My question is how long should I leave them, one week or two weeks? If they lay during that first week, all is well, just want to know how often during the week they lay. If they don't lay during that first week, will it be any use to leave them another week? Those that don't lay will get a black band (which means cull).
