how do i introduce my ducks?

[oliviachilton]

so i have 4 three week old ducklings in their coop right now and they’ve been doing great, but i also have 4 two week old ducklings that my mom wants to move out to the coop today. they’ve never met eachother and i don’t want them to fight. how should i go about introducing them?

How big is the coop, in feet by feet?
Dimensions an pics would help here.

Do you have a wire crate?
..and will it fit into the coop?
