The Blue Ostrich Farm was established in 2001 in the village of Brestnitsa, near the Saeva Dupka Cave. The farm allows visitors to learn more about ostriches, but also about products derived from birds, such as feathers, eggs, leather, meat, etc. These products allow the farm to continue operating. If you are looking for an original gift, here you can find engraved and painted eggs 25 to 30 times larger than those of chickens, with a 1 to 3 millimeter thickness. They are durable and easy to transport.
