On this last Monday, there was a very misfortunate accident that happened in which we lost 2 of our sitting ducks (crested Bali ducks). I have taken the eggs that they were sitting on, & put them in the incubator with some other eggs that were presumed fertile. I don't know how far along the mama's eggs were but I just candled them & 5 of them appear to be about 10 days old or so (give or take). The others look much younger if they are even fertile, it is still very early for those to tell yet. My concern is that they are all at different stages of development so how do I do lockdown when some are so much further along than the others? I'm not sure what to do? Kindest regards & many thanks.
