We have several blind chickens that live together in their own little home. Since they are blind, they are not able to see free choice items such as grit or oyster shell. I tried putting some in a corner dish, but I think that they see anything that is not their normal feed as a treat and they ate it down. I have heard that you shouldn't put the stuff in their feed. What should I do though? What do you think? Would it be ok to just sprinkle a pinch of grit and a pinch of oyster shell in their food every day? I really want to hear what everyone thinks!!
