I have a pair of rouen ducks, (M/F) he is a couple years old and she is about a year old. about a week ago I found 2 freshly laid eggs on the ground under the chicken coop. they were duck eggs. so I got them and put them in my incubator, cause the temps outside were -0. The next day I found 3 more in a box I had put in there for them to huddle up in. I took those and put them in the incubator. that was about 9 days ago and I candled them yesterday and the are all 5 viable. The other day I noticed there were two more eggs back in the same box. I decided to let her set those and see what happens. she has not made any effort to set on the nest for 3 days. I never see her on it or around it, The male will chase the chicken away but he dont go in the box either. Sorry for the long winded speech, but my question is , will ducks wait till they.have a bunch of eggs before the set on the nest? I pulled the 3 new eggs out and put them in the incubator this evening cause I went out after dark and she was setting 20 feet away from the nest. Its like she doesnt know to set on them. should I just have left them in with her? Never raised any chicks or ducks for that matter from an egg so Im kinda green. Thanks in advance.
