Hello, I'm building a new coop with New ducks. I have 3 khaki Campbell's now and in my new coop I am getting 3-4 more ducks I want them for eggs but also I want them to be friendly with with me! I'm wondering which breed(s) will give me the most eggs? If I get different breeds do I need to get more than 1 of each breed or can I get 1 of 4 different breeds? Thanks for any advice at all, and MERRY CHRISTMAS!
