We are new to chickens. We have 3 that we have had since they were 1 day old. They started laying about a month ago. When we got our 1st egg, I bought layer food and started mixing it in with the starter/grower. They are not eating the new food. We tried a different brand, still no. We tried offering them only the layer and they didn't eat it (was only willing to do this 1 day because I didn't want them to starve so put back in the starter). These chickens are picky in general, they won't eat treats (no go on eggs, yogurt, raspberries). They won't eat slugs even when they are hanging out right in plain view (aren't they supposed to eat that sort of thing?) They do like to tear up my dahlias though-yum! Any advice please? I am worried that they will be nutrient deficient on the starter diet.
