I have three Silkies, 2 hens, 1 rooster. They are in a pen all by them selves, but a white pearl leghorn keeps getting in there every once in a while. so im guessing the silkie rooster mated with her because mixed with all the silkie eggs, there was a couple of leghorn eggs, and they hatched the other day, i can tell which ones are silkies, but theres 2 or 3 that is yellow with yellow beaks, they look just like baby leghorns with black spots on there back (may just be dirt). Has anyone had this happen? What will they look like?
