I am trying to figure out the formula to get about five eggs a day (for my family of five). I know this is not precise science, but you all are pretty brilliant. I have 5 Buff Orps, 5 Barred Rocks, and 5 Light Brahmas coming in April. I won't be able to keep them all, and already have a friend to split, but I'm wondering how many to keep. I think I need to make up my mind before I get too attached. Any ideas?
