Since we have chickens the duck world is new to us. I have some questions. 1. Do they need a water dish and something to swim in? or do they drink what they swim in? 2. I put a log in their area thinking they need a purch like chickens do. Do they need the log in there? 3. Do they need a larger area to swim in? 4. Is there anything I can do to help them get comfortable with us? They freak when we go in their cage and my kids want to play with them. They are my daughters 4-H project but she can't catch them (they were born this spring so they are young). This is their cage: the cuties Thanks for your help!
