Im posting this in several sections of Craigslist:
Need to rehome my 3 month old female khaki campbell duck.
Our 4 year old mallard had laid eggs for the first time but was never mated. She seemed very dedicated to the nest so we decided to buy some eggs online to let her sit on. The only egg that survived shipment and natural incubation ended up being a khaki campbell.
The khaki is a lot bigger than the mallard and turns out it's been controlling everything, the pool, food and water, the mallards space and peace of mind. My mallard can't eat, bathe or sleep. I don't have a peaceful way to separate them or the space. I don't want to lose the health and well-being of my mallard and our only solution is to rehome the khaki hopefully before it's too late. If we try surrendering the Khaki to the SPCA there's always a chance they will just put her down.
If you're able to help me take her off my hands or have any information that could help please reply to post I check my email often. Thank you very much.
