I read not to feed ducklings chick starter, so the last two duckling families (six in each one) I raised on corn mash, then went to cracked corn, then to shelled corn. They all did just fine. But when I bought these last two duckling I am raising now, I asked them at Tractor Supply, where I bought them, what they feed the new ducklings. They said they feed the ducklings and the baby chicks Chick Starter, so that's what I've got these two on. They are three weeks old now and seem fine. In another week I'll switch to corn scratch. Farm Girl, what do you feed your new ducklings?
