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.
While ducks do not lay as prolifically as chickens, and do not lay at all in the winter months, duck eggs have a lovely rich flavour and are larger in size than the usual hens eggs. Keeping ducks in the garden or on a smallholding means that you will need to consider birds that are flightless or have their wings clipped.
