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.
Your duck has no idea if her eggs are fertile or not. Most females are not good egg sitters, there are only a few breeds that are actually good nesters. In most breeds, the duck will lay all of her eggs (many times in different places) before she is ready to start sitting on them.ome breeds of ducks are bred so they don't get broody. This way they lay more eggs than a duck that will sit on her eggs. White Pekins are the best known breed of ducks that won't sit on their eggs.
