Most chicken crosses do not have special names.
Silkie crosses are fairly common, so you can probably find some threads by searching on this forum.
Silkie crosses tend to look much alike, no matter what the other parent is. Silkies have dominant genes for crest, 5 toes, feathered feet, and sometimes beards. The other breed contributes the dominant gene for normal feathers. So the chicks all have those traits.
Crosses with black chickens of any breed tend to produce black chicks. The exceptions are when you get white, blue, or chocolate, or when you get white barring on one of those colors.
Crosses with White Leghorns almost always produce white offspring, no matter what color the other parent was.
