I have a 10x 12 completely covered run. I want to see if anyone has opinions about setting up roosting and nest boxes sans a coop. I live in a very humid coastal area. For example here we are in the middle of January and we have a balmy 75 degree day out here. I was thinking of putting up a back wall and two side walls and creating a roosting area and attach some nesting boxes somehow. Im just trying to see what the actual use of a coop is other than extra protection. I don't lock my flock up at night they free range through the day and then put themselves up into their run at night. I have a very small box that they will lay eggs in and then about 7 of my flock will cram in their together the rest will get on the top. I feel like if they had roosting bars they would all use those. If i do what Im thinking they would be protected on three sides and if for some strange phenomenon we get a super dip in temp then I have heat lamps I hang. Im more of the school of thought that they are chickens and they are created to warm and cool themselves if given the right environment. I use the heat lamps only when the temp drops below 40. Anyway any body have a set up similar? Thanks!
