No, it is impossible to breed two birds that sort of make sense and think that you'll get a combination of the two looks. Poultry genetics is so incredibly complex that even people who study it for years still have some difficulty getting what they want. To breed a combination of colors/patterns you need to have a goal in mind and do a lot of research before hand. You can always hatch the eggs that you have, but don't expect anything but an odd outcome from the eggs.
Oh! Well we're still really new, but my adult cochin is by far my favorite chicken ever! And I could only imagine what would happen if my buff and silver laced mated. What exactly would the outcome be?
