Good question KCAmelia, I wonder the same thing - our door is right where the girls roost.Gramma Chick, I do worry that the pop door open down low may cause a draft in combination with the upper vents and window I open for ventilation. Does anyone think that would cause a draft on the roosts? Is anything low supposed to be open? I did think ventilation was okay on all sides above the roosts, though. The roosts are on the other side of the coop, so I guess I was thinking any wind that blew in the pop door would head out the open vent across from it.
