I agree, but I can't crush them up. I wish they were already crushed just a little. My girls pick them up but spit them out again.The soy beans are a critical component of a balanced diet in every feed I am aware of, where they are present. Necessary to boost the overall protein levels and provide a more balanced amino acid profile in an otherwise largely grain diet.
Birds refusing to/selectively eating bits is one of the biggest problems with whole grain feeds, whatever else you might think of them. Like a petulent pre-adolescent refusing to eat thier veggies - when they do it day after day, nutritional imbalances occur which are detrimental to your birds.
and much as I like fresh greens (and my birds, too), the nutrition of fresh greens is different from the nutrition of the seed of the same plant.
Reccomend either crushing/milling that feed so they are less able to "play favorites", or beginning a mash/ferment program, again, to make it more difficult for them to selectively gorge or avoid certain components of your feed.
