I brought home 8 five month old bantam ducks this afternoon, and let them swim in a kiddie pool that was slightly less than half full. They got out after 45 minutes or so, and the pool was removed. They're in a pen on pine shavings. When I checked on them this evening, they were still very wet feeling (my medium ducks are usually dry 30 minutes after a swim). It's in the low 50s overnight. Any reason to be concerned? They've had access to a splashing tub before, but this might have been their first all out splash and "dive."
