**UPDATE** I went out in the yard prepared to "save" my ducklings and what I witnessed changed my mind. Not only had the chickens seemed to lose interest, one of the ducklings(I'll assume this one is a male) has taken to chasing the flock of hens around the yard. I find it hard to believe there's anything more amusing then a day old duck terrifying a flock of chickens. Later in the day I started to worry again because it was getting colder and about to rain. The momma duck had decided to lay halfway under my hibiscus instead of the dry duck house. We changed the bedding and grabbed the ducklings, luring the mom over to the house. This somehow triggered playtime to the ducklings and they made a mad dash to the water bowl half way across the yard and decided it was time for a swim. Momma duck waddled over and watched them play. I decided to leave the yard thinking she would take them in for the evening. Instead, she let them play for awhile longer then resumed her position under the bush. We woke to happy ducklings playing in the rain. So....I'm going to go out on a limb and say my momma duck knows best and leave it be(knock on wood, fingers crossed!!).
