First timer here Got these chicks from school after they hatched. They are 7 weeks old and I'm wondering about gender and breed. I've done a little research, but can't find much. Think the black/blueish ones are Australorps and the little one is a barred cochin? Not sure of the rest. Think I have 2 roosters for sure- the black ones with crazy red combs. Any advice is appreciated! They don't have names, but I've numbered the pictures 1) 2) 3) 4) 5) Delaware Blue? 6) 7) 8) 9) Roosters?
