I have two female ducks, a buff and a khaki Campbell. We had a buff drake until Sunday, it is now Wednesday. Didn't get any eggs from the girls until the drake was gone, now there are three eggs in a nest. The girls like to lay in there together, but I think they are buff eggs. I would like to let them sit and see if we can get some ducklings. I have never done this before and want to do it right. Can I handle the eggs without momma fussing about it? Both girls are very sweet, I just want to make sure they will still accept the eggs after I mess with them. I would like to mark the eggs to keep track of their order, because I might put a couple in an incubator since this is the ducks first time. Any advice is very appreciated, I want to keep my girls happy and make sure I'm doing things right. Thank you!
