This utility model relates to the field of poultry farming equipment technology, and in particular to an environmentally friendly, stackable, detachable, and easy-to-clean duck cage. This utility model provides an environmentally friendly, stackable, detachable duck cage that allows for convenient and quick assembly and disassembly of the cage components, saving manpower and improving cleaning efficiency. The environmentally friendly, stackable, detachable, and easy-to-clean duck cage includes a support frame and duck cage components, with the duck cage components located on the upper part of the support frame. This utility model achieves the effect of convenient and quick assembly and disassembly of the duck cage components, saving manpower and improving cleaning efficiency by pulling the frame outwards, causing the limiting rod to detach from the cage body, the squeezing block to detach from the limiting frame, and the limiting frame to move downwards and no longer restrict the guardrails. Then, the cage body can be removed, and the guardrails and partitions can be removed from the cage body for cleaning.
