I received 6 Welsh Harlequins in the mail on Wednesday. Yesterday evening (Friday) one of them started limping and still is doing so. I couldn’t figure out the cause and the leg doesn’t look broken or deformed to my untrained eyes. She can get around ok and eat and drink. I’ve seen some advice here for older ducklings to isolate them so they heal, but I don’t know if that would be too tough on such a young one. Thank you for any advice.
