When could I put my chicks out with my duck?

[Foxeh]

I have 6 lavender araucana chicks almost 6 weeks old, and a duck(daisy) who I think is less than a year maybe(we found her near our house) we have the duck living in an old cubby house and she has a nice yard. if i put the chicks in the cubby with Daisy will they all be ok together? of should i wait till the chicks are a lot bigger?

You can do that. I put my ducklings with my 2 roosters and they become family. your chicks will probably think they are the ducks kids so they will be alright. at first the ducks may peck at them but will soon stop but if the ducks try to hurt the chicks then maybe take them away.
