LOLTo my untrained eye you have yellow chicks, black chicks with white patches, and yellow chicks with dark patches. LOL! I don't know how you can tell the difference. I look forward to seeing what all these look like when they feather out!
I only know because I marked the hens' eggs.... and separated them during hatch. There are only 2 possible daddys - both are orps.
Now the orps are divided into 2 breeding groups, so next time I won't have to guess the daddy & colors. Last spring when all the schools were hatching, I had too many chicks to easily identify. I marked them with food coloring or leg bands as they hatched. Then I had the fun of getting a little over 30 chicks to care for. When people come to buy chicks, I like to be able to point out the parents, so they'll know what they're getting.
I mark my lavender orps (& black/lav splits) with purple, my EEs with green, etc. DD really liked one one lav orp & went overboard with the purple dye so she could easily find it. I remember one person actually thought that lav orp was a purple chicken.
I wonder what she would have thought about DD's silkie:
