Thieves broke into the building overnight on Monday May 28 by cutting through three doors using power tools.
The stolen Ko-Shamo birds are a mixture of cockerels and hens and a variety of colours.
Police are keen to hear from anyone who saw or heard anything suspicious in the area, as well as anyone who may know the whereabouts of the animals.
