The Duck/Goose feeder has a higher diameter port to allow large size poultry to feed properly.
For this feeder, the feeding port is not reduced to half on the inner side, therefore, we do recommend the usage of feeding port cover during the nights, at least until rats leave the duck coop, looking for an easy access source of feed.
The red cover pieces are adapted to Automatic Gravity Duck/Goose Feeder 25l/17kg with 4 feeding ports
