How do y'all handle the feeding requirements for both? Right now I have my ducks on layer pellets and my 6-7 week old chickens have found their food. They all are free ranging my back yard together. So I know I need to switch of my girls food to something without added calcium for the chicks health. What I y'all do? Grower with free choice oyster shell? They already free choice oyster shell out. Also my second question is how do you handle the feeding and watering devices? My chicks have a container they can't scratched the food out of but my ducks have one of the black rubber bowls. My chicks have a little watered that the ducks can't get to but my ducks have a tall open crockpot insert. Is that dangerous for the chicks? I asked some questions on the chicken boards but since I have ducks it puts a new spin on things.
