For All Birds! Higgins® Protein Egg Food provides your birds with an excellent source of protein derived from both animal and plant sources. Companion bird foods that do not contain animal proteins can be deficient in the necessary amino acids, methionine and lysine. Protein Egg Food is all natural (with added vitamins and minerals) and made with baked whole eggs, whole grain bread crumbs and pure honey. Feeding Higgins® Protein Egg Food will also supplement your bird’s dietary intake with Vitamin A for immunity, Vitamins B12 & E for cell development, Vitamin D for bone and muscular development and Biotin for improved feathering.
