I have 3 Khaki & 3 Pekin ducklings. They are in a 4x4ft brooder with a 'pond'. They are growing SO fast! The pond is now a 2.5in deep, little drawer to swim and drink in. The room is nice and warm, they have a heat lamp and lots of dry area with shavings. I just placed a towel under the little pond. I need ideas on a better duckling pond. Can I see yours?!
