I hope the chickens will eat the millet if I plant it. If they get hungry enough? It is more nutritious than corn, or so I've read. Thinking close to an acre. What grains are in the four-grain scratch?
My deal is that we only feed organic, and in order to make a little profit, we are going to have to grow some of their feed. This breaking even not counting labor is getting old. We live in an area where there are many people selling eggs, but no one else is feeding organic only/true free range. We have 43 layers and 5 roos. We want to go bigger.
Am also thinking of growing pole beans for them, grinding them in fall. Probably scarlet runner, since I saved a lot of them, and they are huge. Figure that's a lot of protein to supplement the organic feed, which contains a lot of soy.
They had their first snow today and tried to eat the little balls (not flakes) that first fell. Maybe they'll eat millet.
I also feed quite a lot from the garden. They got the broccoli and Brussels sprouts plants last week, and all the usual leaves not quite fit for human consumption. I notice that with the snow cover, they ate a lot more grain inside today. This is where it gets expensive.
As for seed companies, I use FEDCO and Johnny's (both in Maine), and Seed Savers Exchange mostly. I need to get my orders in soon. Did place the potato/onion/shallot order, as the organic potatoes ran out before mid-Jan last year. Try FEDCO for best prices.
