I bought 5 muscovies a few months ago and I believed I had 4 females and 1 male. 1 duck has a lot more red in his face, has larger feet, and does not trill so I assumed he was a male. They are all around 6 months old but today I found a soft/rubbery egg. I checked the camera expecting one of the females laid their first egg but the “male” was the one who laid it. Are soft/rubbery eggs normal when they first start laying? I have included a picture, the one I assumed was a male is on the bottom right of the picture of them on the concrete. Any help/advice would be great! Also if you have any ideas on which may be male and which are female please let me know, thanks!
