What do you all usually feed your Delawares from Chick to Hen/Rooster? I have changed recently from feeding layer feed to my hens and rooster that maybe with them to Purina Flock raiser putting a handful of oyster shells and some crushed egg shells in their feed. Plus oyster shells in a separate dish left all the time out there. I have some that won't eat the oyster shells unless it is in their food. I usually use a 18% protein chick starter from Agway. I never have growth issues with that ever. However this Flock raiser said is is for Chick to adult. Since I am new to Delawares what do you use and have success with please?
