I am trying to decide just how many hens to start off with for our backyard farm. We have plenty of room (on an acre). I have a nice shaded spot that has some sun too. I can make a run that could be as big as 12x24 without too much issue. We have a storage shed that I will re-purpose a 6'x10' section as the coop. I figure if they get to be too much of an issue I can more easily sell or giveaway the extra hens, but as they will all be raised from chicks, I figure that we stand a better chance that they will adapt and get along better if we get more to start than trying to add more later at least to start off our little farm. Am I making a big rookie mistake?
