Figure 1. Damaged fans with butterfly shutters For decades, the “slant wall” fan was the preferred poultry house exhaust fan (Figure 2). Testing found that by simply moving a traditional exterior panel shutter (Figure 4) to the intake side of the fan, the air-moving capacity of the fan was increased five to ten percent. Furthermore, the interior fan shutter location resulted in a re ...

According to the latest Bovans layer management guide, at 23 weeks of age the birds should be around 1.7 kg. This is about 200 grams heavier than your birds at 1.5 kg.
