Put a exhaust fan in the chicken house, still need to wire it in but the hard part is done. Not a cheap fan, 14” , 17x17 opening. 1400 cfm, $179. Not easy climbing up a ladder while holding it to put into the hole. The fan I did have was just a house box fan, going to flip it around & run it at night to draw cool air in. The other day it was 80 in the feed room area, at night when I went to close their outside door to the run several had their wings out from their bodies to try & cool off. The next thing if I need more air will be to make a fence panel where the sliding door is, might make a 2nd door to the run and have it be expanded metal to let air in. The big window on the east side opens but dont want it open at night since it has residential house screen in it, A raccoon could go right through that with ease. 3 schools of thought for the fan electrical connection. 1- timer like I use for the other fan & the outside light, have it come on at dawn, shut off at dusk, other fan I will have running at night but be off during the day. 2-a thermostat control, can set to come on at say 90 & run until cools off below that. its about 30-40 bucks. 3- just run it constantly, my “electrical panel” is a 7-outlet power strip with switches on every outlet. Has a circuit breaker & runs to a heavy extension cord going into the garage to a 15amp outlet with breaker in a regular breaker box. Never have had it trip yet. All im running electrically is a floresent light fixture in both feed room/bird area (switched separately), a bug zapper in bird area, a cord for the heated waterer for winter months and a outside led light over the door to go into feed room, and the fan.
2.65 amp draw on this new fan, not too bad. 4-blade but huge amount of pitch to the blades. curious to see how noisy it will be. Rainy now & will be tomorrow but at least I can be under roof for the finish of this project.
