Two days ago I bought three adult ducks. A pair of seven month old male and female buff ducks, and a two year old female khaki Campbell. When can I expect them to start laying eggs here in their new home? They seem happy and I'm doing everything I can to make them comfortable and help them adjust to their new surroundings. I have never bought adult ducks before, so I'm just wondering if it'll be a while before they start laying for me. Thank you!
