Our 9 month old drake lives with a female pekin duck and 4 mixed breed hens. We are hoping he will breed with her as she lays eggs regularly. However, he has little interest in her and in fact prefers to try to mate with the chickens. The female duck dances around him trying to attract his attention to no avail. He just prefers chickens, which they do not like one bit! Any ideas or advice? Thanks.
