I have chicken Feathers and Eggie and they are 17 weeks old- about to start laying! I will put them on a mixture of Layer's feed from Foodland (it smells of raisins and has lots of seeds and corn)and Cleaned Wheat, they will get grit from the stuff they eat in the garden (they free range all day). Will that diet be OK for good eggs or do I need anything else? Thanks, just wondering. I want my chickens to be healthy and lay good eggs!
