I just got back from the store, got her a stuffed reindeer/bear dog toy, and she's snuggled up to it now. I'll see about a mirror sometime soon. I think she did just want to be in the milk jug, she's been sleeping in it all day! I finished the tea from that other gallon jug last night and cut a much smaller hole in it, so she can fit her head in and get water, but she can't climb into it.
I don't want to get another duckling right now because I've already got a drake and a hen, I don't want to end up with 3 drakes lol...I don't know if Indigo is a male or female, I just call her "her" because it sounds better than "it"
if Indigo does turn out to be a drake, I'll find another hen in the spring when I get ready to put Indigo in the pen with the big ducks.
