I have a batch of ducklings from which I'm planning to keep three or four. For once, I want to raise them to love human hands and not think I'm trying to kill them. So in addition to regular treats, I want to keep them on my desk by my computer. I usually do this the first few days anyway, but since my dh and I share an office, I have to take his sensory concerns into consideration: i.e., he thinks they stink (huh? what smell?). Any tips for controlling the odor so I don't stink my beloved out of the room with my babies? Thanks!
