Poultry rearing cage capable of reducing feed mildewing

The utility model relates to a poultry rearing cage, in particular to a poultry rearing cage capable of reducing feed mildewing. Comprising a cage body, a transverse waterline is arranged in the cage body, and a stockline is arranged outside the cage body; the stock line comprises a groove body, the groove body is divided into an outer groove and an inner groove through a partition plate, a gap is formed between the partition plate and the bottom of the groove, and the bottom of the outer groove inclines towards the partition plate. By arranging the outer groove and the inner groove, conveyed feed is stored in the relatively closed outer groove, residual feed exposed in the air is reduced, the phenomenon that the residual feed is pressed on the lower portion when the feed is fed again is reduced, and the phenomenon that the residual feed is mildewed and deteriorated due to long-time accumulation is avoided. The feed is conveyed through the auger, and the situation that a traditional self-propelled feed line m
