You can get some soft alfalfa hay and feed it to them they don't eat the stems cheaper than meal or pellets mine don't free range either due to preds. I've just started mixing my own feed also and I'm watching my birds bloom eating my mix I sprout wheat, oats and boss so far mine love split peas too I can get flax so I add that still buy a local lay mix but it has little soybean in it and it's freshly ground every month or so and I don't use near as much. Soon I'll have grass but from May to Nov I have none.....My eggs have gotten larger and I get lots of them I just set some eggs and from 7, 5 were good @ day 10 only 1 didn't do anything....for pullets pretty good. I don't think I'm saving money but my birds look great and no longer act hungry all the time.....
