When I first started out with chickens they were able to free range all day and only went into the coop at night. After years of doing that with no problems (in hindsight I am really surprised we were able to do that so long with no predator issue), a fox finally found us. I then started only free ranging a few hours a day. That worked for a couple of years. This year I have had to build a run and no more free ranging because I was losing a chicken a day to one or more foxes. I actually had a fox grab one that was 20 feet from me in broad daylight.
Now I have two hoop houses (8 x 8) and a 30 x 30 run. Looking for opinions on how many chicken I can put in there. I am in south GA so they will be let into the run every day all day. I know about the 4 feet in the coop and 10 in the run. I am wondering if the coop space matters as much because they will really only sleep there. I do not want to overcrowd them at all. I have plenty of space so I could make the run bigger. I am more concerned about how many should be in the coop with the understanding that they would only be locked in at night. Looking for opinions.
