I have my Muscovy females incubating their eggs. I had one go missing (Most likely an owl, hoping she just flew off. She got bullied the most) and gave her eggs to another brooding female. It’s been a week so I candled the eggs to check the progress and something seems amiss. Sorry I don’t have pictures so I’ll describe best as I can. Keep in mind the eggs are about ten days apart in development. If I turn the eggs to look around the inside it seems to move. If I tilt it slightly the embryo seems to shift as well. This seems to be the case with all of them. On some of them (I’m guessing the younger ones) don’t seem to be developed much at all. It’s been very windy the past week and there was an extreme temp drop. Are the eggs duds? And if so should I remove them? I do not have an incubator and do not have the money for one currently. Also the last clutch this female had was also a bunch of duds. Is it possible she’s too old or something and that’s why the eggs are messed up? I don’t actually know her age. Should’ve asked the previous owner but didn’t think about it at the time.
