No. In my experience chickens prefer egg shells and will gobble up all of them as fast as you put them out in my experience. I don't bake, microwave, or remove membrane. Just air dry a day or two on a paper plate before crushing.Thank you. Is there any rule of thumb about the ratio of crushed egg shells vs oyster shells or even feed type lime?
Feed type lime is Limestone for Poultry, correct? GC
