I have always had nesting boxes inside of the coop, but I have been told that it is okay keep them outside. I have recently decided to start using 5 gallon buckets for nesting boxes (bolted together and laying on their side outside of the coop) due to the sheer number of new hens we now have. We have huge supply of old oil buckets that need to be recycled somehow and this seems like a good alternative. So I was thinking of building a long row of outside nesting boxes along the fence (50x50 run) since the girls seem more interested in nesting lower to the ground. Thoughts?
