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 duck incubators need larger setting trays as the duck eggs are bigger than chicken eggs. Place the eggs very carefully inside the incubator with their small ends facing down. Another important thing you have to do is to turn the eggs daily except for the last 3 days.
