I have 9 and 7 week old Khaki Campbell ducklings. They appear to be almost full grown and are in their outdoor enclosure during the day and locked up in their coop at night. I give them feed in their feeder each morning when I put them out and they pick at the ground during the day. I guess they are foraging. Should I still be providing them with food and water at night? So far I have been. At what point do I stop feeding/watering them during the night? Do you just stop giving them it? Also, how do I keep the flies/gnats down in their coop?
