We have a basic A-Framed coop in which we have kept 2 chickens with an area in the corner for egg laying. We would like to increase our stock of birds and believe the coop itself will comfortably hold 5 hens. However, in doing so we don't have any room for a nesting box area within the coop. I am intending to build a separate nesting box which would be a separate structure to the coop itself (the coop is in a 30 x 30 metre fenced in area). All forums and postings I've read about nesting boxes has them attached to the actual coop - either inside or as an external attachment, so I would like to know whether there would be any foreseeable problem in having a nesting box as a separate free-standing structure not attached to or part of the coop itself? Any advice welcome.
