The Roxell Fortena is an automatic chain feeding system for hens that lay fertile eggs. The Fortena chain feeding system has large open links taking up 25% less space resulting in less friction between the feed and the chain, this way the feed pellets remain intact and the hens also eat them more easily and faster. The result is that less feed residue is left behind. This chain feeding system has six volume settings which allows you to use your own feeding regimes, ranging from the daily feed portion at one time or spread over several times.
