I read somewhere to feed them breadcrumbs (rather than bits) with soaked in milk - it's worked for me with hen chicks and ducklings - I've never had success with chick crumbs, even when soaking, and end up with most of the bag unwanted - like layers pellets, its like shredded cardboard - give hens the choice of pellets or grain, they choose the grain hands down. We also shred (with scissors) grass for the ducklings and goslings and they yummy it up too. They start eatimg bigger bits about 2 weeks old.
