Does anyone have any knowledge about a duck who appears to have egg dripping from her vent. Took her to the vet who said it was an egg. Prescibed her baytril and calcium. After 7 days no improvement, still dripping. She, tiger eye is eating, drinking, pooing and very lively. Any suggestions from you specialists? Oh yes what is the best thing to use to get the egg of that has attached itself to her rear? Could she be continuely laying soft eggs internally?
