Poor things. If you stop feeding all of this 20 to 25% cracked corn plus also stop mixing the main feed with all of these other treats... Your birds will thank you.Oh sorry alot of people here tell me I feed them too much cracked corn. The main feed is a layer feed and secondary is cracked corn. About 75 to 80 percent layer feed 20 to 25 percent cracked corn. I also supplement this main mix with a little scratch grains, meal worms, oyster shell, poultry grit, manna pro omega 3 maker, harvest delight treats (nuts/seeds/dried vegetables), and those treats with the fish in them.
