This is a Rhode Island White. We were told it was a pulley when we got her with our three other chicks (buff Orpington, barred rock & Australop) but she was much larger when we got her. I assumed she was 2 weeks older than the rest which would make her about 8 weeks now. She's more outgoing than the others and seems to be the dominant one. Her crest is more red than the others & it's looks like she's getting waddles. These are my first chickens so I'm totally new to this. Can you tell if she's a hen or rooster??
