There is provided an apparatus for entrapping game farm birds having an enclosure with a screened closed end and a moveable gate at the open end. The gate is carried by a platform which is moveable between the open end and the closed end. When the platform is brought to the open end, the gate is tipped to the open position by contact of a protrusion from the gate with an abutment fixed to the enclosure. When the platform is moved away from the open end the gate is released and closes behind the birds. Upon reaching the closed end the protrusion from the gate contacts a second abutment to lock the gate in the closed position to restrain the birds for removal.
