1. A trough system for feeding, comprising:
a trough having a side wall portion and provided along a cage row in which a plurality of cages for raising chickens are arranged side by side in a horizontal direction;
a chain of rings that are arranged in the trough in the horizontal direction, each of the rings having a coupling portion; and
an auxiliary tool for feeding that is mounted on a part of the chain in the trough,
the auxiliary tool further comprising:
a hook portion configured to be hooked on the coupling portion of each one of the rings configuring the chain; and
at least a wing portion including an end portion having a V shape or a U shape in a top view with respect to the horizontal direction and extending from the hook portion towards the side wall portion of the trough, whereas
the end portion of the wing portion is brought into pressure contact with the side wall portion of the trough by elastic force to return to an original shape after the wing portion is compressed by decreasing an angle of the V shape or an aperture of the U shape as the auxiliary tool for feeding is mounted on the chain against the side wall portion of the trough.
