i had a baby with rickets and seen some oj with added d and calcium so i bought it and when i asked about everyone told me they wont drink it, they dont like it. well, i had already mixed it in the feed and i guess nobody told my chicks they wernt supposed to like it because they went to town and the rickets did get better.i only gave it once because i didnt want to push my luck. if chickens wont eat something theres a reason for it. mine was hide in the feed.
