Hey guys, Yesterday my husband put a bowl of chick grit in with our 6.5 week old pullets in the coop. Instead of mixing with their food he thought he would attach a bowl to the coop and let them pick at it. THis morning it was empty. How much grit is too much? Will they stop eating it if they no longer need it? We do give them treats (grasshoppers, worms, stale bread, tomatoes) so we have always put some grit in with their feed... Is it ok to free feed grit?
