Well, I say go all 007!
For starters, you’ll want to figure out how many girls you want to have to provide you with enough eggs for you and your family. And a breed too. We predominantly raise these birds here as they are great layers and easy on the quantity of feed. https://www.freedomrangerhatchery.com/details.asp?List=1&Product=7
It’s a common misconception that you’ll get one egg per chicken per day. In Spring with young layers, that’s mostly realistic but they will taper their production as you get into the heat of summer and Fall. Production will decrease to nearly nothing in winter if you live in an area that has short winter days.
Once you get an idea on the quantity of birds, let’s talk about a coop 😉
