OMG, If I only get about 3-4 eggs per week per bird, say 3 conservatively, I would need at least 9 birds to get 4 eggs a day (my need) and this doesn't allow for molt, broody periods bad weather. I am not sure if the 3-4 per week is based on a yearly average and includes higher numbers in summer and lower in winter. Chicken math is harder than anything I learned in school. If this is the case and I want to get about 28 eggs per week, I am guessing that between 12 and 15 birds should do it at the lowest production cycles. It's a given that during the summer, we will be swimming in eggs which is fine (more is better than too few), but the off months are the challenge. Anyone care to speculate on this math and especially if you have experience with this breed or similar.
