I plan on getting two Pekin ducklings soon and I can't seem to find very much information about them online, so I have some questions: 1. How long do they live for? 2. How do I lower the temps by 5 degrees? How long does that last? 3. Can ducklings easily become attached to humans? 4. How do I simulate feeding, swimming, etc.? 5. Is it possible to use a large Rubbermaid tub for the ducklings? 6. When can they start living outdoors? 7. What's the cheapest way for housing outdoors? 8. Can they swim in a SALTWATER pool? 9. How can I introduce them to my dog? Thanks!
