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 will hatch within 28 days normally, except for the Muscovy duck which takes about 35 days to hatch.The mother duck will keep her brood of ducklings together to protect them from predators. Animals like the racoon, turtles, hawks, large fish and snakes are a ducks main predators and they will eat the ducklings.
