Great Feed Price for organic feed found at:
IMO $60 for 48 lbs (even organic whole grain) is not that great unless there is no local suppliers and you are forced to ship feed in... One has to also consider your usage, feeding that feed to my flock would run me about $22,000+ a year, way more than I could ever justify, while someone with only a few birds might very well be able to justify it...
Also unless you are fermenting or sprouting whole grain feeds can cause a lot of waste as the bird picks through it for the desirable grains ignoring or wasting the rest, this can be a problem for anyone mixing their own feeds without a mill...
I have recently been mixing my own pigeon feed since we recently adopted a lost Racing Homer and locally I can only purchase pigeon feed in 50lb bags, way too much for a single bird... With that said we have to ration out his feed morning and evening or else he will sweet pick the grains he likes and ignore or waste the rest of the grains... From my experience chickens and other fowl acts the same way if presented a food they can pick and choose...
