Greetings! Thanks in advance for the help, suggestions and for sharing your projects with me. I will do he same. I have some experience ranging from the 9 hens I raised as a boy of 10 in the 50's thru our family farm where we tend to dozens of birds daily, all free range and managing well. My project as I back off my duties at the family farm (it is my sister's family ranch) my wife and me would like to raise a few (10 or less) in our rural back yard. My "plan" is to build a hen house and a critter resistant run of about 16' long by 8' wide with the house at one end. Our yard is cyclone fenced but since we do get some critters thru that fence we do not want to put our new livestock in harms way..thus the caged ground level run. I will be reading on the formula / suggestions as to how many hen boxes to have and if the run will accommodate 10 hens. I will make that decision after some more research on this site. Thanks again and I am happy to be part of this site.
