With feeding the young chicks uncooked brown rice I would think they would need some grit as well but can not find any mention of that. Any thoughts??
The IMO4 that goes in the brooder is half soil. Also, they always make a point of saying to have floors of chicken houses be soil. So I'm supposing that's where the grit is coming from. I thought of that too and already decided I'd supply them with a bit of sand anyway.
