How important is air flow around and underneath a nest? Last year, I made some enclosures with stacked straw bales and ply board for a roof. One end was left open, but covered with a screen to separate the nest from the rest of the flock. I used a drawer, with straw inside for the nest. The interior measured almost 2' by 3', a little tight, but it seemed adequate to me. My hatch rates in this type of setup was poor. It could have been the two inexperienced pullets that were setting, the lack of space or maybe a lack of air flow. Is air flow even relevant.? I like doing this, but not if it is fundamentally flawed. This year I might try it again, but make the space a little bigger and use something that is up off the ground for a nest. I have heard of people using drawers before, so that may not be the problem. Any thoughts are appreciated.
