I have two pairs laying a normal and a white. The normal one laid 10 eggs and then started setting on them. The white laid 6 and then seemed to just abandon the nest. I left it alone for 4 days but the duck stopped laying and showed no signs that she was going to incubate the eggs. I ended up taking them out. One was cracked so I tried to fix that with nail polish and I put in in my indoor incubator. Just hoing for the best on that one. The other 5 I put with my normal mandarin. She seems to be doing fine with them, but I am wondering if the 15 will be too much for her to hatch? Any thoughts? Looking back, I wish I would have marked the white eggs and started them indoors to see if they were even fertile before putting them with the normal hen.
