I'm so curious to find out what breed and sex these new chicks are... I can post more pics if needed and I put a 'letter' on all the photos to help when you answer...thanks so much for your help!
They're all way too young to sex. As for breed, F, B, and G are probably Cochins. A and D may be Black Japanese bantams and K may be a Rhode Island Red bantam. E is a Barred Rock bantam. I'm not sure about H. The others are likely various varieties of Old English Game bantams (White, Black Breasted Red, etc.).
