Our parent birds work hard and perle morbide allows them to quickly fill up and feed the babies. I have used the green as it's easy to see in the crop if the babies are eating well. We also mix it into the handfeeding syringes and it helps us go a little longer between feedings. All of our bird use it and have been faithfully buying it since 2012. We offer it in finger trays with boiled egg( food processed). We however have tons of mixes that we use it in. We have made spirulina, carrot, egg, carob, and morbide.... Broccoli, carrot, egg, garlic powder, morbide and calcium powder .... Beet water, boiled egg and morbide which is the most beautiful color and the birds love it... Just limitless possibilities with so many health benefits
