My 10 Golden 300s will arrive tomorrow. I went to the feed store to get baby duck food and they said there is no such thing. They use Purina Flock Raiser and said thats what I should use as well. I thought there would be some sort of baby duck food. Even if there is my feed stores don't have it. They have chick starter but it's medicated and I've been told that's not good for ducks. Is the Flock raiser ok for them?
