We have a 4 week old BEI duckling that was the only survivor and we decided to raise her alone. She's been in the house with tons of attention, and often goes places with us, but today we're going to be gone all day to somewhere she can't join us. Unfortunately the weather is pretty yucky -- about 55 degrees and a little rainy. I have a small outdoor pen for her where we put her sometimes when we're outside. It has water to play in and a shelter, and is adjacent to the other ducks so they can all see each other. Aside from her father looking like he's on a mission to take her out, the other ducks and the duckling appear to be mildly interested in each other, or at least the other ducks wonder why the can't have her water too. She's partly feathered, but definitely not totally. So do we leave her outside today where she'll have a lot more room and the company of other ducks, or do we leave her in the house where we know she'll be warm but possibly lonely and bored?
