Duck or goose? I don't know its name exactly. There are 14 of them. My son bought them when they were chicks. Now I don't know their ages, but I expect they are over 3 months old. I can't distinguish males from females. I'm selling them all together, urgently, at a suitable price. Whoever is serious, we won't disagree with them, on the condition that they come and pick them up from the farm because I am not present.
