Hey guys, i currently have a group of quail that refuse to eat eggshell/oyster shell. So, i have an idea, although just an idea. My thinking was that i could throw the eggshells in the oven at around 200 and once they are dried and crunchy, i will put them in a ninja food processor. This should get them to a powdery texture, and i was thinking that i could mix that powder with the water in the quail's rabbit style waterer. Is this a dumb idea or do people do this ? would it work for giving them calcium?
