If you breed frizzle to frizzle, you will get some birds that carry both copies of the frizzle gene. This produces birds with feathers that are brittle and sparse. Always breed a frizzle to a smooth.
That would be my guess too. Well, probably Easter Egger /Silkie cross since EEs are so much more common. The hen in my profile pic is that cross, an your girl looks very similar in stature. We have two Silkie/EEs and they both have that body type. One lays a very light green egg, and the other...
I love mixing them too! Here is Agnes. She is my other Silkie/EE cross, and the hatch mate to Cindy. They look nothing alike! Agnes lays me a pretty little pale green egg daily :)
Now for my questions I have a Golden Sebright male that I would like to cross with one of my Silkies. One of my hens is partridge, and the other is black. Should I try crossing him with Cindy instead?
