Again our livestock vet recommends it and so does our neighboring farmers. I got 24 eggs today out of 24 hens and they have another year and a half before the butcher block. I’ll have more chicks this summer. I’m going to start staggering my layers so I can have a constant supply. My diet for my birds works for me so I’m going to keep at it.I don’t butcher. My ladies are respected pets who provide me food in the way of laying hens. We just want you to know that you are using a product against manufacturer recommendations and no one recommends that. Those who raise meat birds will follow a broiler feed diet. Those are usually broilers. If a dual purpose bird for meat and or eggs ( layers) then they typically follow starter grower and layer complete feeds for the diet as most recommended by poultry experts. Scratch is never recommended above 10% as not a complete feed and only considered a treat. I would suggest trying to wean your birds off so much scratch and taking them back to complete feeds as recommended previously in this post. I would bet you would even have better results for your own purposes.
