Jumbo Feeder with Cone Extension is bigger than the Feeder with the Cone Extension and Grill, it might be filled with 12kg of feed. Bigger diameter allows more birds to get access to feed. As the volume is bigger, it allows to put feed less amount of times, thus saving labour. Jumbo feeder doesn’t have a grill but has a lip which prevents the feed wastage.
The Cone extension eases the labourer to put feed in the feeder thereby saving feed and money.
