Hello, I have perused BYC before and finally decided to join the community. My hubby and I have had chickens and ducks just since last September, so we still have a lot of learning to do. We currently have 1 partridge Chantecler rooster (Cogburn) 1 hen of that breed (had 2 hens originally but one foolishly wondered into the dogs' area). I really love the Chanteclers. We have have 3 Buckeyes, 2 Araucanas, and a New Hampshire Red. We started out with 14 Black Swedish-Khaki Campbell mix ducks but are sadly down to 10. We also have a mixed bag of "inherited" chickens. These are various ages and we can'talk tell who is laying and who is not. We want to cull the non-layers. Other than separating each one is there a way to tell the layers from the non-layers?
