I've got some 1 week old chicks being mother raised and I'm planning on starting to give them some mealworms/insects soon so I'd like to start incorporating grit into their diet. I've heard about over gorging so I'm worried about just putting it out for them to free feed on (I put out some in a dish and a couple of them were really going to town on it, but I'm not really sure how much they are supposed to eat). I've also heard of missing it in with food but that seems to have mixed reviews. Any advice is greatly welcomed!
