We were planning on using an end gable vent, but when I sent my husband to the store he came home with a vent for the eves (b/c it was cheaper) and said we could use it in place of the gable vent...and put in where a gable vent would go. But.... why not just scrap the whole gable vent/eve vent idea completely, keep solid walls, and just put hardware wire over the eves? Would this be enough ventilation? Too much? Also, the roost was going to go up by the eves...so in the winter would this be too much draft do you think? Our coop is only 4x4x4 (almost done) so I wanted to put the roost up as high as I could, i.e. near the eves.
