If you have access to field peas, they are 22% protein at least. Here in farm country, I cannot get them (soy is king) so I just bought some pigeon grain yesterday at the feed store that has 3 kinds of field peas in it. I would like to get some of Purgrain's (Moyer & Sons) 21.5% and mix oats & corn with it, But I got a bag of the 16% yesterday just to see how they liked it. I would have to order the 21.5%. Right now I am going to feed pellets and grain. I also feed lentils (24%) with my sunflowers for scratch. This mix will not save me money, but I would like to get off soy also. A bag of field peas from Countryside is $39.50 delivered here and I checked on split peas at my co-op, but they were $48/50 lbs. I also feed alfalfa cubes moistened and I think they are 17%. Purgrain.com is a neat site where you can see the pigeon mixes and they also explain all the ingredients. The chickens really loved the Austrian peas. I can also get F.M. Brown's pigeon mixes at the local feed mill, so I just have to come up with a mix that I am able to afford! Brown's 20% is $28/50 and the Purgrain (Moyer's) 16% is $28/50. Don't know what the 21.5% is at the feed store. Would like to hear where others find grain ingredients.
