<p>A feeder pan for poultry has a sunk bottom and an edge surrounding the bottom, the bottom being resiliently transformable and the edge being rigid. The bottom can be made of a relatively soft plastic, such as a thermoplastic elastomer, whereas the edge can be made of a relatively hard plastic, such as a polyolefin or a polyamide. The edge may present a profile and may present a closed section.</p> |
