I feed my birds Nutrena Layer crumbles to my big girls and Nutrena Starter/Grower crumbles to my babies. I have bought a small bag of Dumor when I ran out. They didn't seem to eat it as well but I bought pellets and it may have been the change from crumbles to pellets. When I did get their regular feed I smashed up the Dumor and mixed it with their regular feed and they ate it ok. Also when ever I have any Chick Starter/Grower left over, I mix it with their layer and have had no problems. I also give my birds treats of scratch, (oats, unshelled sunflower seeds, once in awhile bird seed, cracked corn etc.); in small quantities as these are treats. I also give them veggies, fruits, most everything that I can grow including all kinds of greens. I do grow a lot of corn and watermelon especially, also tomatoes, squash, root crops, the list can go on. I feed them everything except potatoes. I figure they will eat what they want. I have dishes of granite grit and crushed oyster shells available free choice for them. I do free range them.
