We are a family of 6 and we go through anywhere from 6-18 eggs a week. Not very consistent I know, but sometimes we have scrambled eggs and I bake and we go through lots of eggs and other times we don't. I would like a variety of chickens, and we're thinking about Easter Egger, Speckled Sussex, Welsummer, Maran, Barred Rock, Australorp, Delaware, etc. We are in Utah so it gets cold in the winter and fairly hot in the summer. How many chickens should we start with to get the eggs we need? I was thinking of starting with 4 then in a year or so adding 2 more once the original ones slow down a bit.
