I was looking for something to put in the cage for our indoor chick to cuddle up with. We had tried a stuffed bear, but it wasn't working out. I looked up what people do on BackyardChickens.com, and when I came across the idea of putting in a feather duster, I thought it was right on. Our little guy has had a one for a couple of weeks and he loves it! Yes it is homemade.
During the day it is a toy -- he pecks at it and tries to pull the feathers out. I've had to put it back together three times.
The feather duster is in the heated end of the tank. When he's resting he sits under it like he would a mother hen. The photo on the right is of him settling in for the evening.
