Hi there, our rescue triplet lamb has a very swollen ear and in our case probably from birth trauma. The first vet we saw said just leave it and it will sort itself out but be like a cauliflower ear. The second vet visit, not about the ear, decided to put a needle in and drain her ear but within hours it had filled up again. She’s also started to loose some fleece on her ear, possibly because the skin is quite stretched? Basically vet wasn’t concerned!
