The "Evolution Anti-Migration" Fence is a plastic migration barrier used in larger poultry houses to prevent chicks from conventrating in areas and causing heat stress, inconsistent feed-pan emptying and overworking the litter. Chicks migrating away from end-control pans will create inconsistent feed-line refilling as the control pans do not sense the need to refill the line. The Evolution fence system includes fence sections, u-panels to incorporate low hanging feeder and water lines, and metallic stands to hold the fence in an upright position.
