The powdered alfalfa adds better taste and nourishment to the oats. At this stage the seed may be fed to the birds with satisfactory results. To reap the full benefits of breeding and raising healthier birds more time and preparation is required. Cabbage is an excellent vegetable and the birds will surely eat it with no waste of the additive mix. My birds show no ill effects from any amount of cabbage they consume with the powdered mix.
Carrots are good.
I grate enough carrot and hand squeeze out the juice. I mix a tablespoon of light or brown sugar with the grated carrot. The birds will eat all of it and it helps their digestive system. Now a word of warning - do not use bee honey. Honey may cause crop gas, distended abdomen and toxicity in many birds.
