Supplementation should be limited to no more than 10% of the overall diet.
It is important to carefully follow supplementation guidelines for Harrison’s to be fully effective. Over-supplementation may result in dilution of nutrients.
Never supplement additional vitamins to Harrison’s Bird Foods unless explicitly directed by your avian veterinarian.
Offer certified organic vegetables and fruits in small quantities; select dark yellow meaty or dark green leafy items such as sweet potatoes, carrots, pumpkin, winter squash, broccoli, parsley, spinach, mango or papaya.
It is not recommended to supplement with vitamins, minerals or other bird or animal food products.
For birds with suspected iron-storage disease:
Avoid citrus fruits, tomatoes, kiwi, strawberries and other foods containing vitamin C. Avoid grapes, currants, raisins, liver, red meat, egg yolk or dark green vegetables such as spinach, which may contain high levels of iron.
