How long do you have to wait to move ducks outside? First time having duckings and I have to say they STINK! I have them in a huge plastic and wire rabbit cage with the light suspended on one end so they have a end to get away from the heat. we have had them almost 3 weeks now, and they were probably at least a week old before we got them. I have been changing their bedding (pine shavings) every other day as the mess they make is horrible. I'd like to put them out in a shed with the light and no drafts here soon. What age before they don't need a light? My mom is taking them to her house once they are big enough for no light and I can't wait!
