Marjoram (Origanum majorana) is a perennial herb of the mint family that is known for it's mild, sweet, oregano-like aroma and flavor, especially in the Mediterranean region. It was used by ancient Greeks to make wreaths and garlands and was believed as a symbol of peace, harmony and happiness. Marjoram is also used in both Ayurveda and Yunani medicine to cure various human ailments. Specific uses for marjoram relating to poultry include:
  • Laying stimulant: Several chicken keeper blogs recommend giving laying hens marjoram as a feed supplement; mixing the dried, crushed herbs in a large bowel to add to the feed.
  • Antibacterial: Marjoram may be beneficial against certain harmful bacteria, such as Staphylococcus, E.coli, shigella, proteus, and Pseudomonas.
