I'm taking home an African Grey this weekend, and I have a lot of experience with birds and I'm so excited! I noticed that parrot food is really expensive, and I thought that I could combine (inexpensive) wild bird seeds to create my own parrot blend of seeds. I researched AG seed mixes, and added seeds in the same proportions that were in the commercially packaged foods. I mixed safflower, red millet, oat groats, unsalted nuts, some sunflower seeds, cracked corn, milo, and sesame seeds. I also mixed in cuttlebone powder for calcium, and a high quality vitamin and mineral powder supplement. Will this diet be sufficient enough for an African Grey? If not, is there anything else I could add to make it healthier? Thank in advance!
