LOL yea I suppose. Might be cheaper to but the grains separately and mix them myself.
I won't be much cheaper since the costly ingredients are the peas.
A 50 lb bag of Austrian Winter Peas is about $40
The only "cheap " way of feeding it would be to grow your own
Most anything is "better than scratch" which is just random whole grains.
Pigeon feeds are much higher in protein than layer feed, but the last bag I bought was about $25/ 50lbs
