Hi, I got two tiny one-day-old mallard ducks today! We're keeping them under a heat lamp in a small cardboard box, with wood chips on the floor. Is it all right to have those in there? Cause one was eating the chips (we think) and we want it to stop. Anything else? Temperatures? Swimming? We'd really like to know about swimming, since we don't when to start. On one website someone said she didn't put a pool in the box till day 8. Thanks!
