I'm about to move my -incredibly messy- ducks outside and I wanted to know if I can feed them at scheduled times during the day as opposed to letting them free feed all the time. Half of their food seems to end up in the bottom of their milk jug waterer and they make a gigantic wasteful mess. Not to mention, they'll be out in the yard all day eating whatever is out there for them to eat. When I put them into their little duck barn at night, do they need to have access to water all night long? Just to keep the mess down I'm only going to feed them outside, but I'm not sure how to handle night time water consumption. What are you duck owners using for a waterer once the ducks are outside? I feel like they've grown out of the milk jug waterer and it's getting pretty disgusting anyhow but I don't know if a regular 2 gallon waterer will work. They also have access to a kiddie pool. Any guidance you can provide would be greatly appreciated!
