The chicken plucker has been built and in the next few weeks some of the chickens will be being butchered. I am not sure who is laying and who is not laying. I want to take out some of the older hens and the majoirty of the roosters. Is there a way to tell who is older? or is there a way to figure out who is laying and who is not laying? I would think with 40 some hens I would be getting more than 7-12 eggs a day. Now some days I get closer to 20ish but not always.
