I have 2 Rouen ducks. the female has been wondering off during the day. I didnt think anything of it since im not getting eggs from my chickens either due to molting and the waning daylight hours. Well i found her the other day sitting on a nest of a dozen eggs! Very exciting, but with it being the end of october I am worried if the eggs will survive until hatch. I candled 2 of the eggs this morning after she had gotten off the nest. The two that i candled had lots of veining and what looked like a small fuzzy embryo in it. Im trying to figure out about how far along the eggs are so we can estimate a hatch date for the little fuzzballs. Any info would be greatly appreciated.
