The thing that differentiates bleeding due to implantation and bleeding due to periods is theimplantation bleeding color as explained above. Implantation Bleeding vs. Period. There is little difference between menstruation and implantation bleeding to begin with and the first couple of days can be very confusing.
Ducks can spend a week laying eggs.. the timer for hatching does not begin until they actually begin to sit or brood.. Fertile eggs can be laid and sit and be fine with no mom on them. as long as they dont freeze.
The eggs of most ducks -- including Indian Runners, Call Ducks and Pekins -- take about 26 to 28 days to hatch, while Muscovies require approximately 35 days. After the first 24 hours, you'll need to turn the eggs in your incubator three times daily to exercise the embryo and relieve stress. Around days seven, 12, 19 and 24, you'll remove each egg individually long enough to candle them -- shine a bright light through each egg to look for veins.
