As some of you know I feed a wet mash to my birds. We have a glut of chicken eggs right now so I am adding them to the recipe. I have been putting about a dozen in a five gallon bucket and got lazy the other day and just tossed the eggs, shell and all in the bucket and mixed them in. The shell size is very small, 1/4 inch might be the largest bits found in the mash. The birds are eating it all up, yearlings and mature alike. Now I am getting concerned that they might be getting too much calcium. What do ya'll think?
