Both look to be Bantam Cochins....but not splash. Bottom looks to be a mottled pullet. Top...possibly mottled or maybe will develop into some other color combination; however, if these are both the same age at around 3 to 4 months, the top is definitely a rooster. The bottom is questionable too but I think still a pullet.
Bantam Cochin pullets do not develop much comb until point of lay. Bantam Cochin roosters, however, develop large red combs early....by 3 months of age.
You can see my mottled Cochin hens (one black mottled, the other almost a mille fleur) here, at around 3 months of age:
