I have 13 baby ducks 1 week old. I want them to learn to go in the coop with the big ducks at night due to lots of predators outside. How soon can they join our big ducks? If I put them out too soon I'm afraid they might not go in the coop at night, and they,re too hard for me to catch even with a net. Yet I want tem to learn from the big ducks too so I'm debating how soon to let them out of the house. Maybe I should let 2 out at a time to test...not yet of course at 1 week old. Any advice for me?
