I have a decent sized yard and am contemplating some Hens, nothing big nothing fancy, probably a half dozen, but im open to opinions to what the best number and breed would be best, I am in west metro west Mass. I do have open space behind my lot line , so security is gonna be a must, but I plan on building a sturdy coop. to keep the preds out. Also these will be pets in a sense, so a friendy breed is a must.
