Evening everyone, Looking for opinions on adding in either a whirlybird style passive vent or possibly a more weatherproof roof globe vent. I am in the process of designing a new coop that I plan on making from reclaimed pallets. We have a business pretty close that is a near unlimited supply of various size pallets and if all goes well the coop will be much larger than the current one we have. This last winter/spring there were a few times where bad storms forced us to keep everyone inside due to snow and windchill which was not the best due to the small size of the current coop. Future planning is kind of forcing the redesign. One of the ideas I had for this redesign is adding in a rooftop vent. The coop space that I am planning is probably going to be something closer to 7x10x4-5ish (closer to a small shed than a coop at that point). Looking for opinions on people who have had them on coops or any type of building. I would be concerned about water leakage during the heavy springtime rains we can get. I have run across 'globe vents' that are supposed to be a more weather resistant form of rooftop vent. Third option I would be looking at is boosting the wall air vents with fans either wired into a solar panel/battery system or hard-lined to the house. Main questions: Would a whirlybird/globe vent be worth it? Preference on type of vent? Water/weatherproofing ideas? Roof vs wall vents?
