I'm confused as to what I will be needing to feed my chickens (will be getting them in April). Planning on getting 3 Golden Buff hens, 2 Light Bahma hens and one rooster (kept separate) don't like fertilized eggs when eating them. I've looked around and I just don't understand about the different types. Example: 16% Poultry Layer Crumbles versus 16% All Purpose Poultry Crumbles versus 16% Poultry Layer Pellets. What about Cleaned Cracked Corn, Poultry Grit, Oyster Shell, Poultry Fancy Scratch Grains, & Trip-L-Duty All Purpose Poultry Feed. These are my options to buy in my area and I really don't know what and when I need to be feeding them. I am reading as much as possible about them before they get here but nothing has told me what the differences are and which one is best for egg production.
