This morning I was rummaging through the nest boxes (I haven't done this in a while since I assumed they stopped laying) in the coop and came across eight eggs, four small white ones and four large tan/cream ones. I have three bantam chickens sharing the coop with the muscovy ducks so I assumed the small white ones were a chicken's, and the large tan ones (because they are HUGE and I doubt a bantam could produce something like that) were the muscovies. I want to hatch them so I cracked one of each open to check for fertility, and what do you know, both the white small one and the large tan one was fertile (had bullseye white spot in both). I have one drake and no roosters. I've attached a picture to this post to show the size and color difference and want to know if this was possible to have two different color and size for the muscovies (they're all from the same clutch) or did the drake mate the hens too and, although it won't be viable, could it still be "fertilized" and show up with the bullseye? Do muscovies even have "easter egging" capabilities? I had almost put all the white ones away for eating and had been planning on it, but now knowing they're fertile, if they are muscovy eggs, I'll be hatching them too.
