Today i learned that ducklings can go outside 4-5 weeks if weather is warm out!! THANK YOU GLOBAL WARMING i dont have to keep them inside too long. I am about to order my White Crested drake and 2 welsh harlequin ducks, when i realized: How will they integrate with the chickens? Some of my birds are bantams, others standard. But not full grown. They will be 24-25 weeks when ducks are 4 weeks (ready to go outside). I dont know how big ducklings get in that time or if theyll get picked on or not... How was your success if you had this or a similar situation? How should i go about doing this?
