I was curious if anyone has suggestions on feed and nutrition for chicks and ducklings in the same brooder. The chicks are 4 weeks old and the ducklings are 3 weeks old. They currently are on the chick starter/grower crumbles with 20% protein. I read that ducks protein needs to decrease around week 3 and also they should get a b complex vitamin or nutritional yeast? But then I read elsewhere that they don’t need it. Just want to do the right thing. Any suggestions would be great.
