This nestbowl has a lot of advantages in comparision to the other known nestbowls. Because of the special construction the circulation of the air is very good. The mes is drying very quickly and bacteries, coccidies e. g. get no chance to increase. By using this bowl it is senseful to use nestmaterials like tobacco stalks, straw or nestmats. If using nestmats the young pigeons stay warm, even at low temperatures. Another advantage is, this nestbowl is very easy to clean.
